Vortex pattern of the turbulent flow around a single cube on a flat surface and its heat transfer at different attack angles

Vortex pattern of the turbulent flow around a single cube on a flat surface and its heat transfer... Abstract Experimental results on convective heat transfer from a single cube on a flat surface are presented for different attack angles to the incident flow and Reynolds numbers. The character of vortex formation and the effect of flow structure on heat transfer at detached flow around a cube were studied by visualization. Local heat transfer and heat transfer averaged over the separate faces and the whole lateral surface of the cube were studied. Contribution of separate cube faces to total heat transfer depending on the attack angle was estimated. Data obtained were compared with those published in literature. The reasons for observed differences caused by the effect of many factors: boundary layer thickness, turbulence level of the incident flow, channel constraint, etc., are analysed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Abstract Experimental results on convective heat transfer from a single cube on a flat surface are presented for different attack angles to the incident flow and Reynolds numbers. The character of vortex formation and the effect of flow structure on heat transfer at detached flow around a cube were studied by visualization. Local heat transfer and heat transfer averaged over the separate faces and the whole lateral surface of the cube were studied. Contribution of separate cube faces to total heat transfer depending on the attack angle was estimated. Data obtained were compared with those published in literature. The reasons for observed differences caused by the effect of many factors: boundary layer thickness, turbulence level of the incident flow, channel constraint, etc., are analysed.
