HEAT TRANSFER THROUGH BOILING LIQUID FILMS
By F. RUMFORD The rate of heat flow from a metal wall to a boiling fluid has been measured for water, roluenc, ethyl alcohol and nirric acid. It has been shown that, where more than about 10% of the feed liquid is converted to vapour, the rate of heat vnnsfer is not nfβ¬ened by mass velocity. It is also shown that boiling is not confined to any one zone in a vertical tube evaporator, but probably extends throughout the tube length.

The transient heat transfer between single-crystalline Ge chips and liquid helium is investigated during the application of light pulses with different optical power to the Ge sample. The strong temperature dependence of the electrical conductivity of Ge conveniently serves for monitoring the tempor
Pool boiling heat transfer from a square copper heating surface to liquid helium has been investigated experimentally. The study includes both nucleate and film boiling regimes, the measurements of maximum and minimum heat fluxes and superheats of the heating wall in the pressure region from 0.445 u
Pool boiling heat transfer characteristics of liquid 3He were measured for the first time using the 3He circulation system under saturated vapour pressure at about 1.5 and 2.0 K. The heat transfer surface was a flat plate of 6 mm diameter made of OFHC and set upward. The results show that the A T de
