Enhancement of Wall Cooling by Single-Cavity Diffuser-Type Dimples in Turbulent Flow

Il’inkov, A. V. / Shchukin, A. V. / Takmovtsev, V. V. / Zaripov, I. Sh. / Khabibullin, I. I.

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.
