The present article explains the pool boiling of Cetyltrimethyl Ammonium Bromide (CTAB) with Acetone as base fluid. The boiling is carried out on a copper substrate at different values of heat flux to determine the critical micelle concentration (CMC) of the surfactant. The CMC value is found to be 400 ppm beyond which no heat transfer improvement is observed. The heat transfer coefficient and the super heat temperature are determined at different concentration of the surfactant and different heat flux values. As a result, the heat transfer coefficient is calculated as 19.251 kW/m2 °C at a heat flux of 65.45 kW /m2 with 400 ppm solution. With pure Acetone, this value is 10.557 kW/m2 °C. This shows an improvement in heat transfer of 82.352%.

摘要

The present article explains the pool boiling of Cetyltrimethyl Ammonium Bromide (CTAB) with Acetone as base fluid. The boiling is carried out on a copper substrate at different values of heat flux to determine the critical micelle concentration (CMC) of the surfactant. The CMC value is found to be 400 ppm beyond which no heat transfer improvement is observed. The heat transfer coefficient and the super heat temperature are determined at different concentration of the surfactant and different heat flux values. As a result, the heat transfer coefficient is calculated as 19.251 kW/m2 °C at a heat flux of 65.45 kW /m2 with 400 ppm solution. With pure Acetone, this value is 10.557 kW/m2 °C. This shows an improvement in heat transfer of 82.352%.
