Abstract
Two-phase flow nozzles are used in the total flow system for geothermal power plants and in the ejector of the refrigeration cycle, etc. There exist shock waves or rarefaction waves at the outlet of a supersonic nozzle of the ejector in the case of non-best fitting expansion conditions when the operation conditions of the nozzle are widely chosen. The purpose of the present study is to elucidate the character of the rarefaction waves and the shock waves at the outlet of the supersonic two-phase flow nozzle. In particular, this research treats only shock waves. Two-dimensional basic equations for the compressible two-phase flow are introduced considering the inter-phase momentum transfer. Two-dimensional oblique shock waves occurred in the high speed two-phase flows are calculated by the CIP method. Although the basic equations are controlled by the frozen Mach number, shock waves appear even for a frozen Mach number less than one. Angle of the oblique shock wave of two-phase flow can be calculated from the gas dynamic oblique shock wave relation, if sound speeds of two-phase flow may be used instead of that of gases.
