Numerical Simulation of Microflows Using Hermite Spectral Methods

Numerical Simulation of Gaseous Microflows by Lattice Boltzmann Method

This work is concerned with application of the Lattice Boltzmznn Method (LBM) to compute flows in micro-geometries. The choice of using LBM for microflow simulation is a good one owing to the fact that it is based on the Boltzmann equation which is valid for the whole range of the Knudsen number. In this work LBM is applied to simulate the pressure driven microchannel flows and micro lid-driven...

Numerical Simulation of Mixed Electroosmotic/pressure Driven Microflows

A spectral element algorithm is developed to analyze mixed electroosmotic=pressure driven  ows in complex two-dimensional geometries. The new algorithm exhibits spectral accuracy in resolving thin electric double layers. Mixed electroosmotic=pressure driven  ows are simulated in straight channels. Electrokinetic pumping and the means of producing large pressure gradients in microchannels are ...

Evaluating alternative MPS development methods using MCDM and numerical simulation

One of the key elements in production planning hierarchy is master production scheduling. The aim of this study is to evaluate and compare thirteen alternative MPS development methods, including multi-objective optimization as well as twelve heuristics, in different operating conditions for multi-product single-level capacity-constrained production systems. We extract six critical criteria from...

Numerical Simulation of Complex Viscoelastic Flows using Discontinuous Galerkin Spectral/hp Element Methods

Direct Numerical Simulation of Turbulent Flows Using Spectral Method

Direct numerical simulation (DNS) is the most accurate method of solving turbulence in fluids. In DNS the Navier-Stokes equations are solved on a fine mesh to resolve all the spatial and temporal scales present in the flow. In order to ensure high accuracy of the discrete solution, schemes with low numerical errors are necessary. Spectral methods with their low dissipation and dispersion errors...
