Semi-Analytical Modeling of Critical Heat Flux in Convective Boiling of Nanofluids

What is it about?

Nowadays, utilizing boiling flows due to higher convective heat transfer coefficients is considered favorable in various industries although, the limiting factor in benefiting from these flows is the critical heat flux (CHF) phenomenon. Due to this phenomenon convective heat transfer coefficient of boiling flow suddenly drops to that pf single phase gas flow. therefore CHF must be delayed by various means. using nanofluids instead of pure fluids is a god remedy for avoiding CHF. In the present study, some water-based nanofluidic flows in heat exchanger are analytically studied and the critical heat flux is assessed under different mass flux and volume fraction conditions.
