Proc. ASME. HT2007, ASME/JSME 2007 Thermal Engineering Heat Transfer Summer Conference, Volume 2, 885-892, July 8–12, 2007
Paper No: HT2007-32379
... for enhancing the heat transfer from a surface that would otherwise only be cooled by natural convection and/or radiation. In the presence of an external, flat plate flow, ionic winds distort the boundary layer such that local heat transfer is enhanced at the wall, and recent work has suggested that integrating...

... 03 04 2009 Experiments were conducted to study the effects of spray trajectory angles on heat flux for flat and enhanced surface spray cooling. The surface enhancement consisted of straight fins machined on the top surface of a copper heater block. Spray cooling curves were obtained...

... and 0.3 is 15 to 35% lower than that of a circular cylinder. A case study for an automotive radiator is presented to illustrate comparison of shaped and circular tubes in terms of both heat transfer and pressure drop. Heat transfer enhancement pressure drop lenticular elliptical cylinder cross...

... and the shape factor. A comparative study is performed between the enhancement ratio and both the area ratio and shape factor ratio. Keywords: Pool boiling, Vertical, enhancement, shape geometry. INTRODUCTION It is well known that the modern development of the power station boilers and nuclear reactors...

..., the local Nusselt number approached the fully-developed value in the far field. At the exit of the pipe, L/D = 62.8, local Nusselt numbers were greater than the fully-developed Nusselt number; therefore, heat transfer enhancement was still present at the exit of the pipe. The effect of axial flow...
