SINOPSIS

An experimental study of heterogeneous boiling dynamics in benzene was performed at a pressure of 8 kPa. The test heater was a platinum wire 100 μm diam. The superheat limit of benzene under the test conditions was 502 K. Superheat before boiling close to superheat limit (498-502 K) were attained by transient heating. In these conditions the velocity of the evaporation front in the benzene was 36−38 m/s. The transversal size of the vapor formation varied according to the low τ^0.4. The deviation of the experimental data on the evaporation front velocity from the calculated value is not greater than 20%.
