Heat Transfer and Phase Changex

Analysis of Burning Candle

J.S. Crompton, L.T. Gritter, S.Y. Yushanov, and K.C. Koppenhoefer
AltaSim Technologies LLC, Columbus, OH, USA

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle ... Saiba Mais

Heat Transfer and Phase Change Simulation in COMSOL Multiphysics® Software

N. Huc [1]
[1] COMSOL France, Grenoble, France

This session is devoted to phase change modeling in heat transfer simulations. The great interest in phase change comes from the outstanding thermal performance that it enables in particular for cooling or thermal protection applications. Alternatively, phase change can induce most of ... Saiba Mais

A thermal model to predict the heat generation during the charge and discharge of a battery pack is an essential tool to manage the thermal behavior, performance and life of the batteries. In this work, a battery cell is modeled in COMSOL Multiphysics® using the Batteries and Fuel Cells ... Saiba Mais

Heat Transfer Modeling and Analysis of a Rotary Regenerative Air Pre-heater

R. K. Krishna, R. Ramachandran, and P. Srinivasan
Birla Institute of Technology and Science
Pilani
Rajasthan, India

An attempt has been made to sustain the efficiency of an air pre-heater(APH) in the long run. The APH is modeled using COMSOL Multiphysics in 3D and fed with real life conditions. Upon Heat transfer analysis, the temperature profile was found out and from that, the regions undergoing ... Saiba Mais

Process Modeling and Optimization of Design Parameters in a Falling Film Plate and Frame Evaporator

A. Donaldson [1], A. Thimmaiah [2],
[1] Dalhousie University, Halifax, Nova Scotia, Canada
[2] National Institute of Technology Karnataka, Mangalore, Karnataka, India.

COMSOL Multiphysics® software is used to explore the impact of distributor width on the film thickness, and the resulting sensitivity of overall thermal efficiency in a plate and frame triple-effect evaporator. A stable film is crucial to maintain a minimum wetting rate, to circumvent ... Saiba Mais

Thermo-fluiddynamic Modeling of Laser Beam-Matter Interaction in Selective Laser Melting

K.-H. Leitz [1], P. Singer [1], A. Plankensteiner [1], B. Tabernig [1], H. Kestler [1], L. S. Sigl [1],
[1] Plansee SE, Reutte, Austria

Selective Laser Melting (SLM) offers great potential for future manufacturing technology. In order to extend its applicability for the processing of high melting materials like molybdenum fundamental process understanding is required. This can be obtained by multiphysical simulations ...
