Abstract
The pool boiling heat transfer of trapezoid-shaped copper-foam fins has been investigated at atmospheric pressure in saturated deionized water. The pore densities of copper foams are 100 PPI and 130 PPI, respectively, while the porosity remains a fixed value of 0.95. The foam fins are single-directional and trapezoid-shaped. The parametric study is performed by varying the fin number, fin space, and fin thickness. The maximum heat flux is 1.47Â ÃÂ 106Â WÂ mâ2 in the present study. Boiling patterns are captured by a high speed camera. The results show that the foam thickness significantly influences the pool boiling heat transfer performance, and its effect heavily depends on fin space and fin number.
