Dryout Incipience Quality

The knowledge about the transition point or location of dryout incipience is essential as the dryout exhibits substantial reduction in the heat transfer coefficient. Various parameters, that is, working fluid, heat flux, mass velocity, channel diameter, and saturation pressure, affect the incipience quality for dryout. Kim and Mudawar (2013a) proposed a correlation for dryout incipience quality of saturated boiling mini-/microchannel flow as 

The wetted perimeter to heated perimeter ratio is used for considering the one sidewall heating effect.
