Boiling Heat Transfer in Liquid Metal

Boiling Heat Transfer Characteristics of Immiscible Liquid Mixtures

Cooling technology becomes more important because of the increase in heat generation density of semiconductor chips. Boiling and two-phase flow is expected as one of the most effective methods to cool the electronic devices because of its superior heat transfer characteristics. Because the boiling heat transfer depends on the selection of coolant, the development of liquid mixtures and their co...

Experimental Investigation in Pool Boiling Heat Transfer of Pure/Binary Mixtures and Heat Transfer Correlations

Nucleate pool boiling heat transfer coefficient have been experimentally measured on a horizontal rod heater for various liquid binary mixtures. Measurements are based on more than three hundred data points on a wide range of concentrations and heat fluxes. In this investigation, it has been confirmed that the heat transfer coefficient in boiling solutions are regularly less than those in p...

Pool Boiling Heat Transfer in Water/Amines Solutions

In this investigation, nucleate boiling heat transfer coefficients were experimentally measured during pool boiling of mixtures, consisting of water/monoethanolamine and water/diethanolamine on a horizontal heating rod, under atmospheric pressure. The experiment was carried out below 205 kW.m-2 heat flux, over a wide range of concentrations. These experiments include, measurement of pool boilin...

Flow Boiling Heat Transfer in Microchannels

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...
