An Impinging Jet Heat Transfer Affected by a Small Cylinder
抄録
Heat transfer measurements were conducted for a two-dimensional impinging jet in which a cylinder was mounted rigidly. Air jet was discharged from a rectangular slot having the width ,h, of 15mm and the aspect ratio of 33. The jet Reynolds number was set at about 10,000. The diameters ,D, of cylinders were 4,6 and 8mm and the distance between the cylinder and target plate was ranged within 5 times of the cylinder diameter. Local Nusselt number attained around the stagnation point was augmented a little by insertion of a cylinder, however, mean Nusselt number was not augmented in comparison with the maximum mean Nusselt number attained in a case of insertion of no cylinder.
