A study of transient heat transfer from the heater surface to a boiling liquid

A new method for studying transient heat transfer across a boiling liquid-solid interface is described. The method is based on the use of film temperature gauges with a size of 1000 × 10 μm placed on the heated surface. The effectiveness of the method is verified by measurements of temperature pulsations in the boiling liquid nitrogen and that of the transition from the nucleate to film boiling during pulsed heating.
