Visualization and evaporator resistance measurement in heat pipes charged with water, methanol or acetone

► Visualize evaporation characteristics in mesh wick for water, methanol and acetone. ► Compare Re and Qmax for water, methanol or acetone as working fluid. ► Show good correlation between Qmax with figure of merit for various fluids. ► Correlate Re with evaporating liquid layer thickness. ► Visualize weak nucleate boiling for methanol and acetone.
