Effects of combined ribs and delta-winglet type vortex generators (DWs) on forced convection heat transfer and friction loss behaviors for turbulent airflow through a solar air heater channel are experimentally investigated in the present work. Measurements are carried out in the rectangular channel
An experimental study has been conducted to investigate airflow friction and heat transfer characteristics in a solar air heater channel fitted with the combined triangular rib and theDWturbulators for the turbulent regime
