EFFECT OF HIGH MOLECULAR WEIGHT SURFACE ACTIVE AGENT ON HEAT TRANSFER IN POOL BOILING

Boiling is very complex phenomena also it is very e ffective mode of heat transfer. The boiling phenomenon is affected by different method i.e. act ive and passive method. Addition of surface active agent is active way to enhance the heat tran sfer rate. Heat transfer rate enhancement by addition of surface active method is depend on two parameter one is its ionic nature and other is its molecular weight. In this study we are going to understand the effect of high molecular weight surfactant on heat transfer for that purpose we are using Polyethylene glycol having molecular weight 2909.49 g/mol. The experimental re sult shows that addition of PEG in water increases its surface tension and considerably its surface temperature.
