Natural Convection Effects on the Solidification in Cylinders at Different Filling Percentages

R. Bourisli [1], A. Alshayji [1],
[1] Kuwait University, Kuwait City, Kuwait

The solidification of a fluid in a partially-filled circular cylinder is encountered in a number of industrial processes and in the oil and gas sector. The characteristics of the process depends on various fluid and geometrical parameters. In the current study, a fluid with temperature ... Mehr lesen

Level-Set based Topology Optimisation of Convectively Cooled Heatsinks

M. S. Santhanakrishnan [1], T. Tilford [1], C. Bailey [1],
[1] The University of Greenwich, London, United Kingdom

Introduction Thermal management is a key challenge in development of modern microelectronics systems. This is becoming an increasingly critical area of microelectronics packaging design due to the ever increasing levels of miniaturisation, integration and operating frequency which result ...

Finite Element Method based Investigation of IPMSM Losses

M. Schmidtner [1], C. Markgraf [1], A. Frey [1],
[1] University of Applied Sciences, Augsburg, Bavaria, Germany

INTRODUCTION: This paper investigates the design of IPMSM as drive motor for an electric race car in the competition called Formula Student. A key parameter for electrical motor is the power density which is very important for the performance of such race vehicles [1] to keep the overall ... Mehr lesen

A Flow and Transport Model for Low-Temperature Gaseous Nitrocarburizing of Stainless Steels

J. Feng [1], M. Wettlaufer [1],
[1] Centre of Materials Engineering, Heilbronn University, Heilbronn, Germany

An integrated numeric, thermodynamic, and experimental analysis work was conducted to find out the proper flow and transport parameters of combined chemical species for low-temperature gaseous nitrocarburizing of stainless steels in an industrial furnace built for thermochemical ... Mehr lesen

Heat Transfer Modeling for Thermal Stimulation of Near Wellbore Using COMSOL Multiphysics®

M. Mohammed [1],
[1] Freiberg University of Mining and Technology, Sachsen, Germany

The performance of the oil reservoir is decisively determined by the hydraulic permeability of the rock and the possible flow paths. During the production phase, the petrophysical properties of the rock may deteriorate due to highly viscous oil deposits, especially in the near of the ... Mehr lesen

Optimization of an Explosive Mixture Cooling Process Including a Phase Change

J. D. Wheeler [1], P. Namy [1], C. Coulouarn [2], E. Benade [2],
[1] SIMTEC, Grenoble, France
[2] TDA Armements, LA-FERTÉ-SAINT-AUBIN, France

In the scope of improvement of the industrial “ammunition cooling” process, a COMSOL Multiphysics® model is developed to transfer an existing cooling process. A device filled with a liquid explosive mixture is placed in an apparatus which controls the environment temperature. This ... Mehr lesen

A Plasma Torch Model

B. Chiné [1],
[1] Costa Rica Institute of Technology, School of Materials Science and Engineering, Cartago, Costa Rica

Plasma torches are used in processing of materials and in energy industry for producing plasma. In this work we use the Equilibrium DC Discharge physics interface of COMSOL Multiphysics® to model a DC non- transferred arc plasma torch, under hypothesis of local thermodynamic equilibrium. ...

Compressible Flow Modelling Applied to Depressurization Process

V. Bruyère [1], T. Paris [2], P. Namy [1],
[1] SIMTEC, Grenoble, France
[2] CEA DAM, Is-sur-Tille, France

In order to predict and optimize the design of pipes and reservoirs during a depressurization process, the gas behavior must be precisely understood. Numerical modeling is an effective tool to study and understand the effect of each gas properties on the gas behavior. Nevertheless, ... Mehr lesen

Simulating the Effect of Groundwater Flow and Heterogeneity on Borehole Thermal Energy Storage

M. Possemiers [1], L. De Henau [1], J. Van Steenwinkel [1],
[1] AGT - Advanced Groundwater Techniques, Aartselaar, Belgium

In Borehole Thermal Energy Storage (BTES), also called closed loop ground source heat pumps (GSHP) or closed systems, the thermal energy is stored and recovered with a closed hydraulic circuit consisting of one or more boreholes with vertical heat exchangers. The heat exchangers consist ... Mehr lesen
