EFFECTS OF SURFACTANTS (NH4CL) BEHAVIORS ON NUCLEATE POOL BOILING OVER NICHROME WIRE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 9
Abstract
The heat transfer in boiling can be enhanced byadding small amount of additive in fluid. Addition of small amount of additive in the fluid changes the physical behavior of the boiling phenomenon. Surfactant changes thermo-physical properties of the fluid. Experiments on pool boiling were carried in presence of the surfactant in pure water with an aim to enhance heat transfer in pool boiling by addition of surfactants. Ammonium Chloride (NH4Cl) is taken as test surfactant and added separately in water with varying concentration. The results of surfactant NH4Cl in pure water showed the heat transfer enhancement and above this range no enhancement was observed. Also the trend ofboiling curves in presence of this surfactant in the water, shiftedtowards the lower excess temperature side. Kinetics of vaporbubble in pool boiling phenomena for pure water with and without surfactant was observed in terms of bubble nucleation, growth and its departure.
