Pool boiling heat transfer
WebSystem miniaturization and high heat removal rate are the primary concern of any heat transfer devices,and hence,a lot of investigations are carried out in this field for the last two decades.Pool boiling is considered as one of the efficient ways of dissipating large amounts of heat flux at low wall superheat.Critical heat flux(CHF)is also known as peak heat flux … WebBOILING AND CONDENSATION. Boiling: General considerations • Boiling is associated with transformation of liquid to vapor at a solid/liquid interface due to convection heat transfer from the solid. • Agitation of fluid by vapor bubbles provides for large convection coefficients and hence large heat fluxes at low-to-moderate surface-to-fluid temperature …
