Periodic Compressible Nozzle Flow Caused by Heat Addition Due to Condensation,
Abstract
Periodic, unsteady, compressible nozzle flow caused by heat addition due to condensation in the transonic region is investigated. The experiments were performed in an intermittent tube wind-tunnel. Flow with varying expansion rates, relative and specific humidities, pressures, and temperatures were studied. Measurements were made by pressure and temperature recordings, streak interferograms and high-speed shadowgraph movies. A dimensional analysis that relates the frequency of the cyclic flow to the supply conditions and cooling rate was performed, and correlated with the measurements. Based on a linear approximation, possible solutions of the equations of motion for steady, transonic, diabatic, inviscid flow in the throat region of a nozzle are discussed.
