In this paper, an attempt has been made to estimate the convective heat and mass transfer for pool boiling of sugarcane juice during preparation of jaggery. An indoor experiment was conducted to measure (i) the mass of evaporated water, (ii) the temperature of the sugarcane juice, (iii) the relative humidity above the sugarcane juice surface and (iv) the temperatures at the bottom and side of t...

-Photographic studies of vertical pool boiling for near-saturated conditions were conducted in order to determine the critical heat flux (CHF) trigger mechanism. The studies revealed that, for heat fluxes near CHF, vertical pool boiling exhibits vapor behavior similar to that observed in flow boiling. At fluxes slightly below CHF, the Kelvin-Helmholtz instability creates a wavy layer at the liq...

Pool boiling enhancement through surface modification has garnered the attention of many researchers for extending the limits of heat flux dissipation. Simulated copper chips were used in a pool boiling setup with water boiling at atmospheric pressure. Heat transfer performance of different microchanneled surfaces was compared to that of a plain surface. The results of the study showed that the...

The pool boiling process is one of the most effective heat transfer modes capable transferring large amounts with small temperature difference between heated surface and fluid. In addition, fundamental knowledge processes starting point flow research applications. It therefore no surprise that it has been, still is, subject extensive globally for quite some time a critical analysis now required...

There has been increasing interest of late in nanofluid boiling and its use in heat transfer enhancement. This article covers recent advances in the last decade by researchers in both pool boiling and convective boiling applications, with nanofluids as the working fluid. The available data in the literature is reviewed in terms of enhancements, and degradations in the nucleate boiling heat tran...

Significant amounts of heat flow can be removed with small temperature differences by boiling. This process is used in a variety industries, e.g., cooling electronics, digital circuits, power sources, etc. Heat dissipation from equipment that generates significant flows involves the movement thermal energy through wall into fluid. In present study, this mechanism was analysed during boiling Nov...
