Experimental study on heat transfer characteristics between spherical solid particles and cylindrical surfaces

This study experimentally investigates heat transfer between corundum particles (1–3 mm) and cylindrical surfaces. Results show that reducing particle diameter from 3 mm to 1 mm increases the heat transfer coefficient by 50–100 W m−2 K−1. A 100 °C rise in wall temperature enhances the coefficient by...
