functionwall
Free convection, wall
Extends from Buildings.HeatTransfer.Convection.Functions.HeatFlux.BaseClasses.PartialHeatFlux (Partial function for convective heat flux).
Information
This function computes the buoyancy-driven convective heat flux as
q̇ = h ΔT,
where ΔT is the solid temperature minus the fluid temperature and h is the convective heat transfer coefficient for a wall, computed as
h=1.3 |ΔT|0.3333.
