Partial model to build a heat source with convective and radiative component
Information
Overview
Partial model to build a heat source with convective and radiative components. The parameter ratioConv determines the share of convective heat. The input is always a relativ input between 0..1.
Assumptions
The surface for radiation exchange is computed from the area of the emitting component. For more information see AixLib.Utilities.HeatTransfer.HeatToRad
An input of 0 leads to a surface area of zero and, thus, to division by zero. For this reason a limitiation for the surface has been intoduced.
