modelLocalDuctConvectiveHeatFlow
heat transfer model for locally resolved rectangular ducts in quasi-counter
flow arrangement
Extends from PartialDuctHeatTransfer (partial model for rectangular duct heat transfer models).
Information
This heat transfer model calculates the convective heat flow for local distribution using the function convectiveHeatTransferCoefficient. The heat flow is calculated as follows.
Q̇[i] = α[i] Ccross[i] Asurface[i] ( heatPorts[i].T - Ts[i] ) nparallel
