Boiling for Science

Mixture Boiling

This chapter provides the engineer and the researcher with correlations and models for the prediction of the critical aspects of the boiling heat transfer of mixtures. This chapter offers a reliable, hands-on resource for solving common problems across pool boiling and flow boiling applications such as miscible mixtures, refrigerant/lubricant mixtures, additives, and refrigerant/nanolubricants....

Development of a Boiling Regime Map and Gravity Scaling Parameter for Pool Boiling Heat Transfer

Modified Boiling System for Better Sugar Quality

A new boiling system for the production of improved VHP sugar is proposed. This modified scheme requires only minor changes to pipe-work in the factory and it is estimated that steam consumption will only be increased marginally.

A New Heat Balance for Flow Boiling

Abstract Recently, one of the authors suggested calculating void fraction, an essential element in thermalhydraulics, working with the ‘thermodynamic’ quality instead of the usual ‘flow’ quality. However, the standard heat balance is currently stated as a function of the ‘flow’ quality. Therefore, we should search a new energy balance between the mixture enthalpy, based on ‘thermodynamic’ quali...

Nanowires for enhanced boiling heat transfer.

Boiling is a common mechanism for liquid-vapor phase transition and is widely exploited in power generation and refrigeration devices and systems. The efficacy of boiling heat transfer is characterized by two parameters: (a) heat transfer coefficient (HTC) or the thermal conductance; (b) the critical heat flux (CHF) limit that demarcates the transition from high HTC to very low HTC. While incre...
