Flow of gases below standard atmospheric pressure, sometimes called low-pressure gas flow. The flow may be confined to pipes between a chamber or vessel to be evacuated and a pump, or it may be the beam of molecules issuing from an orifice into a large evacuated chamber or the plume of exhaust gases from a rocket launched into the upper atmosphere, for example.

For example, the study of gas flow with rarefaction parameter very much greater than unity (Knudsen number Km >>I) has been treated by the gaskinetic theory of molecular flow; and the study of gas flow with rarefaction parameter very much less than unity (Knudsen number Kn File Size: 1MB.

The mathematics of low-density gas flows is carefully developed without being obnoxiously dense. My favorite feature of this book is the successful balance that is provided between theoretical development (equation derivations) and practical applications including (1) numerical simulation results and (2) numerous tables of engineering values 5/5(1).

Abstract. The considerable interest in rarefied gas dynamics, which developed during the late fifties and the sixties, as a result of spectacular space programs, has led to the study of a great number of theoretical and experimental problems concerning flows of neutral and ionized gases, and to a rich harvest of original : J.

Smolderen. The rarefied gas analysis using NET-IV has been developed only recently [20, 21]. In this framework, EIT occurs as a particular case of NET-IV when the internal variables are identified to be the Author: Róbert Kovács.

The rarefied gas flow through a short channel into a vacuum is studied by the direct simulation Monte Carlo method. The mass flow rate through the channel is calculated over the wide range of gas rarefaction. This study demonstrates that the effects of the gas molecule–molecule interaction and the gas–surface scattering can make a.

The articles in this compendium are organized under 10 main topics. The aim of this book is to present the concepts, methods and applications of kinetic theory to rarefied gas dynamics.

After introducing the basic tools, problems in plane geometry are treated using approximation techniques (perturbation and numerical methods). These same techniques are later used to deal with two- and three-dimensional problems. in calculations of rarefied gas flows.

Using these models it was possible to obtain numerical results on rarefied gas flows in the transition regime. Thus in a numerical investigation of rarefied gas flows began in its systematic form.

For a long time, it was possible to solve only the model by: 4. Simulation of Rarefied Gas Flow in the KATRIN Source L. Kuckert1 1KIT, Karlsruhe, Germany Abstract The KATRIN experiment at the Karlsruhe Institute of Technology (KIT) will measure the neutrino mass on a sub-eV range.

Therefore the electron spectrum of the beta decay of Tritium. Free molecular flow describes the fluid dynamics of gas where the mean free path of the molecules is larger than the size of the chamber or of the object under test.

For tubes/objects of the size of several cm, this means pressures well below 10 −3 is also called the regime of high vacuum, or even ultra-high is opposed to viscous flow encountered at higher pressures.

In the framework of the classical gas dynamics, no steady flow is induced in a gas without an external force, such as gravity, by the effect of a temperature field.

In a rarefied gas, on the other hand, the temperature field of a gas (often in combination with a solid boundary) plays an important role in inducing a steady flow. In the present article, we introduce various kinds of flows Cited by: A new type of a rarefied gas flow, which was found numerically by the research group of the first author, is demonstrated by a simple experiment.

It is a steady flow induced by the edge effect of a uniformly heated plate. The experiment is carried out in a standard Cited by: On the apparent permeability of porous media in rarefied gas flows according to the gas kinetic theory, this only results in an increase of the correction factor with the Knudsen number, which.

Among their topics are the main equations and approaches to solutions of the problems in rarefied gas dynamics, modeling the flow of continuous media, determining the aerodynamical characteristics of the returnable space systems, and the general models describing turbulent flows. The direct simulation Monte Carlo (DSMC) analysis of two- and three-dimensional rarefied gas flows requires computational resources of very large proportions.

One of the major causes for this is that, along with the multidimensional computational mesh, the standard DSMC approach also requires a large number of particles in each cell of the mesh Cited by: After presenting basic theory and various simple flows, such as unidirectional or quasi-unidirectional flows and flows around a sphere, the author discusses additional topics, including flows induced by temperature fields, which are typical in rarefied gases; flows with evaporation and condensation; and bifurcation of flows in rarefied : Birkhäuser Basel.

The theory and computational techniques of a gas-kinetic unified algorithm,, have been established and used to simulate the one-dimensional, two-dimensional and three-dimensional gas flows from highly rarefied free-molecular flow to continuum flow regimes with the whole range of Knudsen by: The combined effect of a variable collision frequency and a correct Prandtl number on the structure of a Knudsen layer is investigated.

A new collision model having both properties, but simple enough to be amenable to a simple solution, is proposed and used to solve the problem. Results turn out to be in exceptionally good agreement with the experimental data of Reynolds, Smolderen and Wendt Cited by: 5.

A rarefied gas flow through a thin slit caused by a small pressure difference is studied on the basis of the kinetic equation. The Bhatnagar–Gross–Krook model equation is solved numerically by the optimized discrete velocity method.

The gas–surface interaction is assumed diffuse‐specular. It is shown that the dependence of the mass flow rate on the gas–surface interaction law is Cited by: rarefied gas flows in the transition regime.

Thus in a numerical investigation of rarefied gas flows began in its systematic form. For a long time, it was possible to solve only the model equations.

Practically, all classical problems of gas dynamics (Poiseuille flow, Couette flow, heat transfer. Many macroscopic equations are proposed to describe the rarefied gas dynamics beyond the Navier-Stokes level, either from the mesoscopic Boltzmann equation or some physical arguments, including (i) Burnett, Woods, super-Burnett, augmented Burnett equations derived from the Chapman-Enskog expansion of the Boltzmann equation, (ii) G regularized 13/26 moment equations, rational.

In addition, a comparison is made using a “hydraulic radius” in the equation which Weber developed for rarefied gas flow through cylindrical tubes. Good agreement between theory and experiment give a high confidence level to the theoretical by: 2.

The field of rarefied gas dynamics encompasses a diverse variety of research that is unified through the fact that all such research relates to molecular-kinetic processes which occur in gases. phase change kinetics, etc.), (c) kinetic-theory modeling, (d) Monte-Carlo simulations of molecular flows, (e) the molecular kinetics of species.

Gas flows take place in a number of micro-electro-mechanical systems (MEMS). Since the dimensions of the MEMS are within μm range, it is necessary to take into account the gas rarefaction effects in investigations of these flows. This paper presents the solution and analysis of isothermal compressible gas flow through micro channels with slow varying cross section under low Mach number Author: Nevena D.

The flow is driven by temperature gradients along the channel walls. The channel itself is made of segments of different sections.

Both the channel section and the temperature profile have periodic variations along the channel axis. This situation is that of an experiment reported in, e Cited by: Macroscopic transport models for rarefied gas flows: a brief review scopic transport equations for rarefied gas flows. Since the book was written, a considerable amount of work on the R13, and the R26, equations was published, and the present review can be considered as Boltzmann equation (Section 3), and a summary of the theory of.

These satellites function way up in the sky, where there is bare. A rarefied gas flow into vacuum through a tube of finite length is investigated over the whole range of gas rarefaction by the direct simulation Monte Carlo method. The nonequilibrium effects at the inlet and outlet of the tube have been considered by including in the computational domain large volumes of the upstream and downstream by: The mass flow rate of a rarefied gas through a long channel with a rectangular cross section has been calculated based on the model kinetic equation for the whole range of the Knudsen number and in the wide range of the height-to-width ratio.
