The Efficiency of One Method of Machineless Energy Stratification in a Gas Flow

Abstract eng:
The efficiency of a method for machineless gasdynamic energy stratification based on heat transfer between sub- and supersonic flows separated by a thin wall is studied numerically. A model flow consisting of two sub- and supersonic laminar boundary layers separated by a thin heat-conductive plate is considered. In the first part, pure-gas flows with different Mach and Prandtl numbers are investigated and, in the second part, the effect of an admixture of small evaporating droplets presenting in the supersonic boundary layer on the efficiency of the considered energy stratification scheme is examined. The Saffman force acting on the droplets in shear flow is taken into account.
