This paper describes an experimental investigation which has been carried out with distilled water with the range of heat flux and pressure covering 7,400-28, 000㎉/㎡h and 0.42-1.0332㎏/㎠abs, respectively.
In this experiment, Nickel coated mirror surface heater of 5㎝ O.D. was used as a heating source.
The conclusions summerized as follows;
1. The useful correlation of the test data for the heat transfer coefficient is presented as a function of the pressure.
α/α_s=c×p 0.18
where α is the heat transfer coefficient and α_s is the heat transfer coefficient at atmospheric pressure and p is the pressure, C is constant.
2. The bubble diameter near the heating surface and rising velocity increased with the heat flux.
3. A decrease in pressure results in the decrease of the number of nucleation sites and the increase of the bubble volume.
4. Bubble rising velocity differences are increased maximumly up to 200% of that at atmopheric pressure.
