Definite Regimes of Boiling | Heat Transfer | Thermal Engineering

Whether the boiling phenomenon corresponds to pool boiling or forced circulation boiling, there are three definite regimes of boiling associated with progressively increasing heat flux. These regimes have been identified in Fig. 12.8 which shows the relationship between heat flux (or film coefficient) and the temperature excess (ts – tsat); ts is the temperature of the hot surface and tsat [...]

Boiling and Heat Transfer: Correlation | Thermal Engineering

The heat transfer during a boiling process is governed by the convective heat transfer equation; Q = h A Δt Where, Q is the heat flow rate, h is the boiling film coefficient, A is the surface area and Δt is the temperature differential between the heating surface and the saturated liquid; Δt = ts – tsat. The boiling is [...]
