A literature survey was made on boiling. This includes bulk boiling, natural and forced convection boiling, twophase flows,pressure drops, and the stability phenomena. Experiments were performed with special emphasis on the forced convection subcooled nucleate boiling heat transfer inside an electrically heated tube of small diameter and large L/D ratio. Instrumentation was provided to measure temperatures, variations of temperatures, pressures, pressure differentials, mass flow rates, and flow observations. Test results showed the effect of pressure, of inlet subcooling, and of mass velocity on heat transfer. Effects of heat flux on tube wall and fluid temperatures were also observed, particularly in relation to temperature waves and flow stability. He at transfer correlations were obtained for both the non-boiling and the subcooled nucleate boiling inside the test section.
