STUDY OF SELF-SIMILAR PISTON PROBLEM IN TWO-PHASE RADIATING GASES

Print ISSN: 2319-1023

Abstract

A di fferential approximation for the equation of radiative transfer in a grey gas is applied to study the eff ect of thermal radiation in case of one dimensional unsteady shock generated by a piston with velocity vp = htn, in case of two-phase mixture of gas and dust particle. Numerical solutions in region between the shock and piston problem are presented for the case of general opacity and transparent limit. The influence of particle volume fraction for various cases are discussed and is concluded that though the general behaviour of velocity, density, pressure are unaff ected, yet presence of particle volume fraction shows a rising tendency in velocity, density and pressure but a decreasing tendency in net radiative flux.
