Experimental study of the forces associated with mixed convection from a heated sphere at small Reynolds and Grashof numbers. Part I: cross-flow Academic Article uri icon


  • The present paper addresses the issue of mixed convection from a small heated sphere in cross-flow configuration. The sphere is suspended in an electrodynamic chamber (EDC), where it is heated by a focused laser beam up to several hundred degrees above room temperature. As a result, there is free convection from the sphere, with the Grashof number smaller than 0.01. Then, a horizontal forced flow is applied and gradually increased in a quasi-static manner. Horizontal flow velocities are in the range 0–0.1 m/s, providing very …
