ABSTRACT

Modeling of quenching behavior has been gaining significant attention in the research community. However, it has been claimed that nanofluids exhibit an enhanced heat transfer coefficient. In the present investigation, a one-dimensional, semi-analytical model has been proposed to predict the quenching behavior of deonized water and Al2O3 nanofluids with a volume concentration of 0.005% at mass flow rates of 4, 6.5, and 9 g/s. A comparison of the experimental results clearly indicates that this semi-analytical model can be used to predict the quenching behavior of diluted nanofluids within acceptable limits.
