Simulation of processes in heat sensors based on solution of inverse problems in heat conduction

Abstract

Experimental data on the second virial coefficient and viscosity are generalized using (m-6) Lennard-Jones potentials with four and three parameters for a group of rarefied gases consisting of quasi-spherical molecules with tetra- and octahedral symmetry. Analysis is made of correlations of the parameters of potentials with the structural characteristics of molecules and critical temperatures of substances. The parameters of three-parameter (m-6) Lennard—Jones potential for nine molecules of CH4, CF4, CCl4, C(CH3)4, SiCl4, Si(CH3) 4, SF6, MoF6, and WF6 are included in the EPIDIF information-and-computation database (epitaxy and diffusion processes) on the transport properties of rarefied gases and gas mixtures.
