Abstract
In this study, experiments are performed to understand the critical heat flux (CHF) enhancement using nanofluids, with special emphasis on pool boiling. Al2O3 and CuOnanopowder were purchased from Sisco Research Laboratories (SRL) having particle size of ∼25 nm and ∼40 nm respectively. The critical heat flux measurement at atmospheric pressure for three different concentrations (0.01gm/lt, 0.1gm/lt and 1gm/lt) of Al2O3 and CuOnano particles suspension in water was taken and pool boiling experiment was carried out at atmospheric pressure using 0.111mm Nichrome wire submerged in each solution. The significant enhancement in CHF has been recorded with each of the nano solutions as compared to the pure water. With increasing the concentration of thenanoparticles the CHF was found to increase as compared to deionised water.
