Description

This model describes linear heat convection between a material surface and gas or fluid flow. The basic equation is:

p.dQ = (p1.T - p2.T)*Gc;

where p1.T is the temperature of at the surface and p2.T the gas or fluid temperature. Gr is the thermal conductance which is function of the surface area A and the convection coefficient h:

Gr = A*h;

In most cases h is not contant but a non-analytical function of the gas or fluid speed and other poperties. In most cases Gr is experimentally defined. Therefore G is given as an input signal.
