Know Thy Solver- PART I: Introduction and Motivation For Segregated NSE Solvers

A successful CFD analysis workflow consists of the following key elements (sometimes by repeating cycles, and sometimes with additional elements as-per-cause): Definition CFD modeling goals according to the model problem at hand: Physics gives us a description of reality or in other words, a model, by such CFD modeling goals should conform to the level …

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 …

Advanced ANSYS Fluent Course – Turbulence Modeling

The attached presentation is taken from TENZOR advanced ANSYS Fluent course presenting the portion of the course summarizing turbulence modeling (workshops we have created specifically for the course are included in the final version). We've tried to keep as many representing important topics inside, but of course (keeping in mind the short time and the …
