CFD prediction of critical heat flux in vertical heated tubes with uniform and non-uniform heat flux

Nuclear Engineering and Design, 2018
Abstract In this paper, Eulerian Two-fluid model coupled with extended wall boiling model was used to simulate the departure from nucleate boiling (DNB) in vertical heated tubes under high pressures by using STAR-CCM+ 10.04. Based on CFD approach, new methods were developed to predict the critical heat flux (CHF) in both uniform and non-uniform ...

Heating of a uniform wafer disk

International Journal of Mechanical Sciences, 2007
The closed-form heating response of a thin uniform circular wafer is obtained, in view of a new processing method for semiconductor materials. A strain energy formulation is obtained expeditiously using Gaussian curvature and associated structural concepts.

Temperature distributions in fins with uniform and non-uniform heat generation and non-uniform heat transfer coefficient

International Journal of Heat and Mass Transfer, 1987
Abstract Temperature distributions in a straight fin of rectangular profile (or in a cylindrical fin) with uniform and non-uniform internal heat-generation characteristics and non-uniform heat transfer coefficients are derived analytically. The heat transfer coefficient is assumed to be a power function of the difference between the temperature of ...

Merit of non-uniform over uniform heating in a porous cavity

International Communications in Heat and Mass Transfer, 2016
Abstract Energy transport in a bottom-heated porous cavity utilizing uniform and non-uniform heating is important as a fundamental study as well as from the perspective of various industrial and technological applications. The present work reports enhanced thermal energy transport using sinusoidally non-uniform heating over uniform heating from ...
