Hydrodynamic and Thermal Behavior of Journal Bearings using Upwind Petrov-Galerkin FEM
(Taylor & Francis, 2008-03)
A novel approach to modeling plain journal bearings is presented. The journal is assumed to be cut open at the oil supply groove and modeled in Cartesian coordinates. The streamline upwind Petrov-Galerkin (SUPG) finite ...
Eulerian FEA With Volume of Solid (VOS) Application in Metal Forming
(ASME, 2010)
The adaptation of the volume of fluid method (VOF) to solid mechanics (VOS) is presented in this work with the focus on metal forming applications. The method is discussed for a general non-uniform mesh with Eulerian finite ...
Rotating stall simulation for axial and centrifugal compressors
(Taylor & Francis, 2017-04)
This study presents a numerical simulation of the rotating stall phenomenon in axial and centrifugal compressors with detailed descriptions of stall precursors and its development with time. Results showed that the vaneless ...
Sensitivity analysis of control parameters in particle swarm optimization
(Elsevier, 2020-02)
Particle Swarm Optimization (PSO) is a powerful nature-inspired metaheuristic optimization method that may determine optimal solutions of engineering problems in fewer evaluations compared to other optimization methods. ...
Large eddy simulation for a deep surge cycle in a high-speed centrifugal compressor with vaned diffuser
(The American Society of Mechanical Engineers - ASME, 2015-06)
This paper presents a computational study for a high-speed centrifugal compressor stage with a design pressure ratio equal to 4, the stage consisting of a splittered unshrouded impeller and a wedged vaned diffuser. The aim ...
Experimental study of interaction of twin liquid jets on stationary and moving surfaces
(ASME, 2014)
The interaction between twin liquid jets impacts the heat transfer at interaction region. In this paper, the interaction of twin circular free surface long water jets with typical industrial parameters impinging on stationary ...
Hydrodynamics of Twin Water Jets Impingement on a Flat Horizontal Moving Surface
(Ninth International Conference on Computational Fluid Dynamics (ICCFD9), Istanbul, Turkey, July 11-15, 2016, 2016)
The interaction of twin round free-surface water jets impinging vertically on a horizontal moving surface is numerically studied. Jets flow rate (15, 22, 30 L/min) and substrate velocity (0.6, 1.0, 1.5 m/s) were systematically ...
Suitability of Project-Based Learning (PBL) in Mechanical Design Education
(In Proceeding of the WSEAS International Conference, 2005)
This paper discusses the suitability of Project-Based learning (PBL) in mechanical design education. We first introduce project-based learning and highlight its main differences with problem-based learning. We discuss the ...
Coupled finite element modeling of piezothermoelastic materials
(International Society for Optics and Photonics,, 2007)
The governing equations of piezo-thermoelastic materials show full coupling between mechanical, electric, and temperature fields. It is often assumed in the literature that in high-frequency oscillations, the coupling ...
A Modified Particle Swarm Optimization Scheme and Its Application in Electronic Heat Sink Design
(ASME, 2010-06)
Particle Swarm optimization (PSO) is a robust stochastic evolutionary computation technique which is based on the movement and intelligence of swarms. In this paper the PSO algorithm is modified to improve its performance ...
