Experimental Investigation on Electorhydrodynamically Enhanced Heat Transfer in Partially Open Enclosures

Experimental investigation on heat transfer enhancement by applying electrohydrodynamics (EHD) in partially open multiple fined enclosures with different aperture position has been performed. The enclosure had five thermally and electrically insulated faces; while one face was copper finned plate with an aperture located on its opposite face. In the present study, different parameters including electric current, number of fins, aperture position, and corona polarity were investigated. It was concluded that heat transfer enhancement is proportional to the supplied current. Higher number of fins can lead to further heat transfer enhancement and as the location of aperture is shifted upward, the heat transfer coefficient is improved more significantly by EHD.
