Experimental investigation of circular free-surface jet impingement quenching: Transient hydrodynamics and heat transfer

► Heat transfer estimation during jet impingement quenching of stainless steel. ► Transient experiment with initial steel temperature of 900 °C. ► Inverse analysis to determine the heat transfer rate. ► Jet velocity has a strong influence on the wetting front growth. ► Boiling heat transfer rate increases with jet velocity.
