Turbulence prediction has an enormous impact airliners fuel budget, weather information, automotive industry, turbomachinery, biomedical industry and could be easily linked to many other aspects of our daily lives. A lot of focus has been given to the prediction of turbulence through numerical modeling to level of physical fidelity depending on the goal of the practitioner (ranging …
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 …

Predictions for CFD in 2030
"Prediction is very difficult, especially if it's about the future..." - Niels Bohr Growing up as the child of two software engineers, mathematics and computers were an inseparable part of my life. My father always had these wonderful science-related stories and the patience to follow up on each and every question I had.I remember when …

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 Adaptive Simulation (SAS) – cutting on your computational budget in an unsteady manner
“Turbulence is the most important unsolved problem of classical physics…” – Richard Feynman. Nothing would be as cost-effective for the flight industry as the ability to cut substantially on fuel budget. From a CFD perspective, such a goal could be achieved in a much more straightforward manner if a full airborne vehicle simulation could be supplied, still keeping high fidelity of the physics. …
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 …
