Bromley temperature effects

B) R.L. McKisson L.A. Bromley, "A New High-Temperature Calorimeter , USAEC (US Atomic Energy Commission) Report UCRL 688 (1950) (A calorimeter for use in the temp interval 600 to 1500° K contg a thermostat of molten tin surrounding a cavity in which the sample is placed. The calorimeter is resistance-heated, and control of the thermostat temp to lQ.5°C is effected by means of a modified "single-speed floating control . 

Boiling liquids outside horizontal tubes Film boiling (above critical Atj) l n Tkv Pv(pL PtOffXc D. l1,, Nucleate boiling (below critical At,) Value of h depends on At/, type of surface, and materials involved (critical At/ for water as temperature drop from heating surface to liquid is approximately 45°F). Bromley t For saturated liquids on submerged surfaces film coefficient h,0 is for conduction through the vapor, no radiation effect is included. 

Bromley s equations are consistent with reality in that they predict a minimum value of h. As the solid temperature is increased, two counteracting effects occur. The values of k, and AT both increase. At first the... 

In 1973, Bromley (B3) presented two equations that he felt adequately correlated the effect of temperature on the B parameter of his equation (4.44). They are ...
