.BuildingSystems.HAM.ConvectiveHeatTransfer.Gaps.alphaGap

Information

This function computes the convective heat transfer coefficient for a gap between two parallel surfaces with the gap distance d, the gap height h, the surface temperatures T1 and T2 and the gases air, argon, krypton, xenon and SF6.
