Oscillating piezofan effects on natural and forced convection flow in a vertical channel with protruding heat sources

Journal of Thermal Engineering
The current work investigates the flow characteristics and convective heat transfer performance of a vertically-oriented piezofan in a channel with wall-mounted protruding heat sources. A 2D numerical model is developed in COMSOL Multiphysics to simulate

Gradient models of moving heat sources for powder bed fusion applications [PDF]

International Journal of Heat and Mass Transfer, 2022
In this paper, we derive closed form solutions for the quasi-stationary problems of moving heat sources within the gradient theory of heat transfer. This theory can be formally deduced from the two-temperature model and it can be treated as a generalized

A simplified thermal approximation method to include the effects of Marangoni convection in the melt pools of processes that involve moving point heat sources

Numerical Heat Transfer, Part A Applications, 2021
Processes that use moving point heat sources to temporarily create localized melt pools (metal additive manufacture and fusion welding) have a flow phenomenon due to the surface tension gradient.

Computation of melting with natural convection inside a rectangular enclosure heated by discrete protruding heat sources

Applied Mathematical Modelling, 2013
Abstract This paper presents the results of a numerical investigation of the heat transfer by natural convection during the melting of a phase change material (PCM, n -eicosane with melting point of 36 °C) contained in a rectangular enclosure. This latest is heated by three discrete protruding heat sources (simulating electronic components) placed ...

Natural convection to air from an array of vertical parallel plates with discrete and protruding heat sources

International Journal of Heat and Fluid Flow, 1995
Abstract Numerical and experimental studies are carried out on natural convection heat transfer to air from an array of vertical parallel plates with protruding and discrete heat sources, such as IC packages. Two-dimensional (2-D) Navier-Stokes and energy equations including heat conduction through the plates and heat sources are numerically solved ...
