It is well known that the efficiency of sheet-steel production depends on the achievement of required parameters and the low cost of the product. The causes of divergence of sheet parameters from the required values are analyzed. It is shown that the

Based on the classical concept of atomic motion and the Goodman and Wachman lattice theory, we have developed a computer program to model the equilibrium and non-equilibrium scattering of helium atoms by 3D tungsten crystal lattice with allowance for

The effect of the microchannel surface structure on the free-molecular gas flow is studied by the test-particle method. Simulations are performed for channels whose surface either is obtained by means of statistical modeling or is reconstructed from

Errors of pressure measurement are considered. The error as a function of the pressure for a vacuum gauge rated at up to 1000 Pa is calculated as an example. It is 0.15 ≤ δp/p ≤ 0.2% over a pressure range of 14 ≤ p ≤ 1000 Pa and it increases

We have derived an equation of thermal perturbations by deduction from a physical model for deformation vacuum gauges with bellows as the elastic element. The model can be used to analyze the temperature zero drift of micropressure gauges, to divide

This paper presents the results of experimental studies of the lengthwise distribution of the total and static pressure and the total flow of carbon dioxide in symmetrical neutralizers. These distributions are found to depend on the flow regimes and

A measurement is made of the thermal polarization which develops in a gas flow in a nonuniform channel due to the dependence of the mechano-caloric heat flux on surface roughness.
