2-D and 3-D modulated porous coatings for enhanced pool boiling

Comparative experimental study on pool boiling performance of porous coating and solid structures with reentrant channels

“…Liter and Kaviany [20] theoretically and experimentally demonstrated that the 3-D modulated porous coatings constructed by sintered copper powders enhanced the CHF up to 3 times compared to a plain surface in pentane. The 2-D modulated porous coatings with parallel V-shaped grooves in the later studies of Kaviany's group [21] also presented a notable enhancement of pool boiling. Motivated by the above, Ji et al [22] comprehensively explored the enhancement feasibilities to prepare parallel or cross-linked V-shaped channels in uniform sintered copper powder surfaces in acetone.…”

Pool boiling heat transfer on copper foam covers with water as working fluid

“…Recently Min et al [8] developed a new fabrication method (hot-powder compaction) to make 2-D and 3-D modulated coatings for enhanced pool boiling performance. The results show that the maximum measured critical heat flux (q CHF ) of 2-D and 3-D modulated coatings are 3.3 and 2.0 times that of the surface without coatings (plain).…”

Experimental Study of Enhanced Nucleate Boiling Heat Transfer on Uniform and Modulated Porous Structures

“…Kaviany et al (2001Kaviany et al ( , 2006Kaviany et al ( , and 2009 analytically and experimentally investigated the characteristics of pool boiling on modulated and uniform porous structures using pentane as the working fluid. The geometry of the porous media and the particle size used in the porous media, was specifically designed according to the physical properties of pentane.…”
