High mass flux flow boiling and critical heat flux in microscale

A comparative study of experimental flow boiling heat transfer and pressure characteristics in straight- and oblique-finned microchannels

“…13, with the local vapour quality as indicated for each data point. The CHF values increase linearly with mass flux for both type of microchannels structure, and similar behaviour has been reported in the literature [9,[33][34][35][36]. This is easily understood because a larger heat flux is required to reach the same vapour quality at a higher mass flux.…”

Flow boiling of ethanol/water binary mixture in a square mini-channel

“…Water is one of the most commonly used operating fluids as it is easily accessible and also a component in many organic binary mixtures. Kaya et al [8] used water and examined the effect of high mass flux on critical heat flux (CHF) in fluid boiling, observing that CHF increased with increasing mass flux. It was also observed that high heat removal rates could be achieved (more than 300 MW/m 2 ) by combining short heated tube length, high mass flux and small hydraulic diameter.…”

Heat transfer characteristics of R-134a in a converging-Diverging nozzle

“…Most work has been done with lower mass fluxes than considered in this paper. One paper experimentally studying critical heat flux did study cases with mass fluxes in this range-up to 38,000 kg m −2 s −1 [27]. Only critical heat flux was reported; no heat transfer coefficients were given.…”
