Critical Heat Flux in Boiling and Condensation Formulas

Critical Heat Flux describes the thermal limit of a phenomenon where a phase change occurs during heating,thus causing localised overheating of the heating surface. And is denoted by q_Max. Critical Heat Flux is usually measured using the Watt per Square Meter for Heat Flux Density. Note that the value of Critical Heat Flux is always negative.
