| Pool boiling - the boiling that occurs when a stationary heater transfers heat to an initially inactive stationary liquid. The main objective of this work is to develop correlation for maximum heat flux in pool boiling of saturated liquids Acetone, Isopropanol, Methanol and Freon 113. In present study, one more dimensionless group is introduced to modify equation. The Prandtl Number, Boiling Temperature (Saturation Temperature), Critical Temperature and Freezing Temperature (Melting Temperature) are combined in form of equation to develop the accuracy of maximum heat flux equation. Margin of error is reduced for maximum critical heat flux equation up to +/- 8 percent by development of this revolutionary rule. The new correlation represents a 50 percent improvement over Sun and Lienhard equation, which is most widely used in present literature. Liquid density and vapor density becomes equal at saturation stage when the critical temperature for liquid is reached. Therefore, it is considerable that the critical temperature is one of the important factors affecting maximum heat flux for saturated liquids. |
