Numerical heat transfer in a solar air heater duct with punched delta-winglet vortex generators

Numerical heat transfer in a solar air heater duct with punched delta-winglet vortex generators

The flow topology and thermohydraulic performance of a novel designed punched delta-winglet (P-DW) placed on the absorber of a solar air heater duct are numerically explored. The effects of geometrical parameters, namely, the relative winglet pitch, PR = 1–2 and the relative punched hole size, dR = ...
