The present work is carried out to investigate heat transfer and friction factor characteristics of fluid (air) flow through turbulent channel i.e. parallel plate heat exchanger for different geometry and designs parameters, with a bottom plate applied to uniform constant heat flux thermal boundary condition, and upper plate is provided with a insulated condition. The fluid domain is designed u...

The computational fluid dynamics is concentrated on the forced air cooling of the CPU using a heat sink. This paper utilizes CFD to identify a cooling solution for a desktop computer, which uses an 80 W CPU maximum whereas this number will be increased in the range of 70-120W in the forthcoming desktop computer systems. This paper considers the optimal plate fin heat sink design and cylindrical...

Electric circuit analysis determines the voltage and current distribution in an electric circuit due to applied source voltages or currents. In a static (DC) electric circuit analysis, the voltage and current distribution in an electric circuit is determined that is subjected to applied DC source voltages or currents. In a harmonic (AC) electric circuit analysis, the voltage and current distrib...

FEA-based simulation has become an integral part of engineering practice. Sophisticated FEA software such as ANSYS are used in industry for the design and analysis of complex engineering systems. However, the use of such software in the undergraduate mechanical engineering curriculum has been limited so that students are not prepared adequately to make appropriate use of these powerful tools. A...

The paper introduces an electro-mechanical transducer finite element (EMT) for the strongly coupled simulation of micro electro-mechanical system (MEMS) devices in the commercial finite element analysis (FEA) package ANSYS.

The present paper discusses the pressure loss through the spiral heat exchanger (HX) proposed in the ELSY (European-Lead cooled SYstem) project. An approach based on CFD (Computational Fluid Dynamics) using the commercial code ANSYS CFX has been used for exploring the flow through the HX. The HX consists of perforated double inner and double outer walls, as well as an innovative spiral design o...

This paper presents a numerical and infrared experimental study of thermal and grain growth behavior during argon tungsten arc welding of 443 stainless steel. A 3D finite element model was proposed to simulate the welding process. The simulations were carried out via the Ansys Parametric Design Language (APDL) available in the finite-element code, ANSYS. To validate the simulation accuracy, a s...

Thermal management is an important part during the development of a hybrid or electrical vehicle. This concerns several components in the electrical network of a car, the most important being power electronics and a battery pack. Electrothermal simulation is required at the system level in order to choose the best regime that complies with all thermal requirements and an important problem is ho...

One of the main obstacles to including transient dynamic effects into the performance functions of a structural optimization is the high computational cost of each time-dependent simulation. The focus of this paper is on the application of model order reduction techniques to reduce the transient analysis time for the attainable optimization process. The software mor4ansys developed at IMTEK per...
