In thermodynamics, the heat transfer coefficient or film coefficient, or film effectiveness, is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ΔT ). It is used in calculating the heat transfer, typically by convection or phase transition between a fluid and a solid. The heat transfer coefficient has SI units in watts per square meter per kelvin (W/m /K).

WebHeat transfer. Heat transfer is thermal energy in transit due to a temperature difference. A topic you may have touched on in Chemistry is thermodynamics. Thermodynamics deals with equilibrium processes and endpoints. It doesn’t give us rates. Heat transfer deals with temperature gradients and non-equilibrium phenomena. Webcauses this heat transfer. The heat transfer continues until the two objects have reached thermal equilibrium and are at the same temperature. Heat can move from one point to another in three basic ways: by conduction, by radiation, or by convection.
