Heat Transfer Performance of Metal Fiber Sintered Surfaces
TLDR
In this paper, the boiling heat transfer coefficient for the optimum surface structure was investigated on stainless steel metal fiber sintered surfaces with Freon 11 (Rll) as the working fluid.Abstract:
Boiling heat transfer performance on stainless steel metal fiber sintered surfaces is experimentally investigated with Freon 11 (Rll) as the working fluid. The boiling heat transfer coefficient for the optimum surface structure gives a tenfold improvement over a smooth surface. The nondimensional specific parameter including all design parameters is introduced to explain the trend of the performance of various kinds of metal fiber sintered surfaces. Moreover, the metal fiber sintered surface clad with titanium film is suggested to be appropriate to an evaporator for Ocean Thermal Energy Conversion (OTEC)system.read more

Development of Composite Wicks for Heat Pipe Performance Enhancement
George Franchi,Xiao Huang +1 more
TL;DR: In this article, composite wick heat pipe configurations were fabricated from a biporous structure comprised of fine nickel metal powders sintered onto layers of coarse pore copper mesh, and the effects of both enhanced evaporation heat transfer at the liquid/vapor interface and the extension of the capillary limit were explored.
