Convection

Convection

Convection is used to model heat transfer of a surrounding fluid or gas of a given temperature. The amount of heat transferred through the surface is given by the transfer coefficient. This essentially specifies how conductive the fluid or gas is on the surface.

Units

The transfer coefficient id given in W/(mm² °C) or W/(m² °C).
The bulk temperature is given in °C (Centigrade) or °K.
