Air convection correlations are different for Buildings, Energy+ and IDEAS #506

damienpicard commented 8 years ago

I've noticed that we do not use the same correlations in IDEAS.Buildings.Components.BaseClasses.InteriorConvection than the ones used in Buildings.HeatTransfer.Convection.Functions.HeatFlux.

The ones in energy+ are also different: http://bigladdersoftware.com/epx/docs/8-0/engineering-reference/page-021.html

I can give you papers with 20 different formulas for this correlation ... with a range of factor 10.

The best we could do is to provide multiple options with an enumeration, but I'm not sure if there's a need for this?

rubenbaetens commented 8 years ago

In that case i would stick to the well-knowns, like ASHRAE Fundamentals, Khalifa, Awbi & Hatton, ...
