Abstract
Experimental data on average heat transfer and flow resistance were obtained in a rectangular channel with arrays of single-cavity diffuser-type dimples on the channel wall. Simulation of flows past arrays of single-cavity diffuser-type dimples was performed for different inclination angles of dimples. Heat transfer experiments are described and discussed.
