Abstract An experimental investigation of the Critical Heat Flux (CHF) and heat transfer coefficient (HTC) of two-phase heat transfer of de-Ionized (DI)
water, pool boiling was conducted using several kinds of sintered copper microparticle porous uniform and modulated structures. The modulated
porous structure reached a heat flux of 450 W/cm2
and a heat transfer coefficient of 230,000 W/m2K. The thick and thin uniform porous structures
achieved CHFs of 290 W/cm2
and 227 W/cm2
, respectively, and heat transfer coefficients of 118,000 W/m2K and 104,000 W/m2K. The mechanisms
for the dramatically improved CHFs and HTCs were identified with assistance of More >
