Compressibility Effects on Turbulent Heat Transfer of Natural Convection in a Square Cavity
Heat transfer in turbulent flows is one of the essential topics in power plants and thermal-based engineering. This study aims to analyze the effects of density changes due to heat transfer in a turbulent environment—which is usually neglected because it

Turbulent-Prandtl-number models for liquid lead-bismuth in triangular rod bundles
BackgroundIn order to accurately predict the heat transfer characteristics in the sub-channel of fuel assembly for the low Prandtl number fluid, it is necessary to select a suitable turbulent-Prandtl-number model.PurposeThis study aims at the ...

Topology Optimization of Turbulent Flow Cooling Structures Based on the k-ε Model
Topology optimization (TO) is an effective approach to designing novel and efficient heat transfer devices. However, the TO of conjugate heat transfer has been essentially limited to laminar flow conditions only.

The rate of information transfer as a measure of ocean–atmosphere interactions [PDF]
Exchanges of mass, momentum and energy between the ocean and atmosphere are of large importance in regulating the climate system. Here, we apply for the first time a relatively novel approach, the rate of information transfer, to quantify interactions ...
