ShareK-factors for HVAC ducts: numerical and experimental determination.
Author(s) : GAN G., RIFFAT S. B.
Type of article: Article
Summary
A new method for determining the velocity pressure loss factor (k-factor) of HVAC duct fittings has been established. The method presented in the paper is based on computational fluid dynamics (CFD) and experimental measurements. The k-factor was calculated from the measured pressure loss and air velocity for the duct fitting. Optimum predictions of pressure loss and k-factor were achieved using CFD with a combination of the standard k-e turbulence model and quadratic upstream interpolation scheme.
