Abstract : The purpose of the study was to investigate the heat transfer near a stagnation point in two-phase flow. Heat transfer coefficients were experimentally determined for sixteen air velocity and water pressure combinations. Water momentum rate and slip velocity ratio was determined for each combination investigated. Results indicate heat transfer increases with increasing momentum; and with increasing slip velocity ratio when the water drop size is held constant. Results further indicate that mass ratio strongly influences heat transfer. Stagnation region heat transfer coefficients are the same order of magnitude for various geometries. (Author)
