An analysis of the effect of orientation on the heat transfer in a scaled model pin fin heat sink utilized in Light Emitting Diode (LED) lighting has been carried out using numerical method. The present study involves natural convective heat transfer that takes place in particular heat sink. A pin fin type heat sink has been studied since they are widely used in LED lighting systems which in tu...

The paper presents the design and simulation of double spiral Pt-based microhotplate (MHP) for gas sensing application. A platinum resistor of 52 Ω has been designed and simulated on a 0.3 micron thick SiO2 suspended membrane of size 40 × 40 μm using ANSYS. The SiO2 membrane of size 40 × 40 μm and thickness 0.3 micron has been fabricated successfully by bulk micromachining in <100> orientation ...

The switching device turn-on and turn-off process will produce high-frequency electromagnetic interference, based on the finite element method ANSYS software with powerful computing capabilities, has been widely used in complex electromagnetic field calculations. In this paper, ANSYS software to model and analyze the insulated gate bipolar transistor (IGBT) and quantitative distribution of elec...

The paper deals with finite element model for analysis of electromagnetic forming process of thin metallic sheets. The investigation starts with the FLUX simulation of transient electromagnetic field phenomena, continues with a transient structural analysis using ANSYS Structural under loads previously evaluated and ends with an ANSYS Multiphysics fully coupled analysis. The paper emphasizes th...

This paper presents the design analysis of saddle support of a horizontal pressure vessel. Since saddle have the vital role to support the pressure vessel and to maintain its stability, it should be designed in such a way that it can afford the vessel load and internal pressure of the vessel due to liquid contained in the vessel. A model of horizontal pressure vessel and saddle support is creat...

The software mor4ansys that allows engineers employ the modern model reduction technique to the finite element models developed in ANSYS is presented. We focus on how one extracts the required information from ANSYS and makes the model reduction implementation not dependent on a particular sparse solver in C++. We discuss the computational cost and give examples related to structural mechanics ...

ABSTRACT: This paper describes analysis of deep beams subjected to two point loading with three different L/D ratios (1.5, 1.6, 1.71) using Non-linear Finite element method (ANSYS 9.0 software) in order to investigate the stress and strain distribution pattern at mid-section of the beam. In ANSYS 9.0 software, SOLID 65 and LINK 8 element represent concrete and reinforcing steel bars. Non-linear...
