Inserted plates inside the duct flow are proposed in order to enhance heat transfer coefficient, however the inserted plates cause a significant pressure drop, In order to decrease the pressure drop, the inserted plates with slits were employed. Numerical calculations of two-dimensional, laminar, and steady state conditions of duct flow with and without inserted plates were carried out. Air, as a heated media, with range of velocities 0.5m/s-1.5m/s and ambient temperature 20℃ was heated by using 50℃ isothermal duct wall. The calculation results show that the setting of inserted plates enhances the heat transfer coefficient significantly but pressure drop also increase. The presence of slits hole in the inserted plates decreases the pressure drop significantly but the heat transfer coefficient decrease slightly. The calculated streamlines, isotherms, vector velocity, local and average heat transfer coefficient, total heat transfer, and required fan power (pressure drop) are presented.}, pages = {541--544}, publisher = {日本機械学会}, title = {A Numerical Study on Heat Transfer Enhancement and Pressure drop Decrease of Heat Exchanger by Setting Inserted Plates in Duct}, volume = {15}, year = {2005}, yomi = {キシナミ, コウキ and サトウ, カズヒコ and ダイマルヤ, マサシ and スギヤマ, ヒロム and スズキ, ジュン} }
