Abstract:

Free and forced convection quenching studies of hydrodynamic shapes are presented. Effects of subcooling and surface condition on heat flux and vapor layer stability are included. Motion picture studies of characteristics of vapor-liquid interface configurations are discussed. These include vapor layers generated by sublimation and with a chemically reacting surface in combination with film boiling. Forced convection heat transfer and friction drag measurements in water are presented and compared with theoretical predictions from a companion investigation. Large friction drag reductions were observed. Author
