Investigation of the cooling of a high-temperature surface by a dispersed coolant flow

A modernized experimental setup diagram is presented for studying the cooling of a high-temperature surface with a dispersed coolant flow. The results of an experimental study of unsteady heat removal from a target with a temperature exceeding the Leidenfrost temperature are presented. The cooling curves are obtained, the regions of effective heat transfer are determined. The primary experimental data were obtained during stationary heat transfer in the following range of operating parameters of the coolant: mass water flow rate 0.0038 ÷ 0.0145 kg/s; water pressure 0.4 ÷ 0.2 MPa, induction heating power 7 ÷ 20 kW.
