A series of pool boiling experiments are performed in thermodynamically saturated, gas saturated, and pure-subcooled FC-72 using 25-, 50-, 75-, and 390-μm-diameter platinum wires. Comparisons of nucleate boiling characteristics are made between the various fluid-state/wire-size combinations. The effects of dissolved gas concentration on heat transfer are significant and are found to depend on length scale and heat flux. This discovery of a heater size and heat flux impact on dissolved-gas boiling enhancement provides insight into experimental results from previous investigations.
