On shock waves in two-phase flow: Effects of inter-phase heat transfer andslip

This paper is one in a series reporting on the gasdynamic analysis of two-p hase flows in which a parametric treatment of the nonideal effects provides a convenient framework for analysis. The focus of this paper is on establi shing the general gas dynamic relationships for normal shock waves in mixtu res of a perfect gas and a nonreacting condensed phase. While the effects o f slip and mixture mass fraction are examined, the main emphasis here is on the inter-phase heat transfer which occurs due to the increase in gas-phas e temperature across the shock. The results show a significant influence of heat transfer on the conditions under which shocks may exist. Moderate-to- large effects in the shock downstream conditions are predicted.
