Understanding The Realizable k-ε Turbulence Model

Most of nowadays CFD simulations are conducted with the Reynolds Averaging approach. Reynolds Averaged Navier-Stokes (RANS) simulation, the "working horse" of industrial CFD is based on the Reynolds decomposition according to which a flow variable is decomposed into mean and fluctuating quantities. When the decomposition is applied to Navier-Stokes equation an extra term known as the Reynolds …

Thermal Analysis and Cooling Solutions for Electronic Equipment – a comprehensive guide

TENZOR - Authorised channel partner ANSYS In order to reduce development time, electronic equipment manufacturers and PCB designers need to ascertain the thermal aspects at the earliest possible stage of the design process. In the early days of thermal management thermal analysis to supply such information was conducted mainly by thumb ruling and simplified correlation-based calculations, rendering somewhat of …

Scale Resolving Simulation – Overview

It's quite amazing how Computational Fluid Dynamics (CFD) progress has been tremendous in the past half a decade. Moore's Law vision of an exponential growth in computational resources lived up to its expectation and it's by many predicted to keep doing so for  the next 20 years if not more. Moore's Law applied to CFD One huge leap forward …

Numerical Schemes in CFD- Part I – The Cell-Reynolds Problem

Part I of Numerical Schemes in CFD shall regard an important topic approaching conventional CFD and the process of discretization of the governing partial differential equations of a fluid flow by approximating the differential equations with a system of algebraic ones and linking the discrete nodal values of velocity, pressure, etc. There are three broad methods employed for …
