Lumped thermal element for heat convection

Description

This is a model of linear heat convection, e.g., the heat transfer between a plate (solid, left) and the surrounding air (fluid, right). It may be used for complicated solid geometries and fluid flow over the solid by determining the convective thermal conductance Gc by measurements. The basic constitutive equation for convection is:

Thermal conductance is specified by the input signal connector (top), since Gc is never constant in practice. For example, Gc may be a function of the speed of a cooling fan.
