How to Benefit from Decades of Experience in Turbulence Modelling

David Fletcher from LEAP discusses the importance of the 3rd Turbulence Best Practices guide recently released by Florian Menter and his team at Ansys.
This latest BPG documents the key best practices in RANS turbulence modelling, with comprehensive coverage of all widely-used 1-equation, 2-equation and Reynolds stress models.

How to Use Expressions in Ansys Fluent (and convert from CEL)

Summary of a recent webinar presented by Prof. David Fletcher on how to take advantage of the powerful python-based expression language now available in Ansys Fluent. Examples shown included the use of expressions starting from scratch, plus examples showing how to convert your existing CFX CEL into Fluent expressions.

Guest Blog by ECU-R: Analysing F-SAE Aerodynamic Flow Fields Using CFD

Guest blog by ECU-Racing on how the team uses CFD simulation to drive aerodynamic design improvements, explaining how CFD simulation results provide help identify problematic aspects such as flow separation, undesirable flow structures, and poor use of flow energy which can then lead to new ideas which can be tested in CFD to improve the overall flow around the car.

Helping EO/IR Sensors to accurately detect & track hypersonic vehicles

Learn how recent developments in Ansys provide a new “optical CFD” workflow to help more accurately simulate the complex interactions between the flowfield and electromagnetic fields in the Electro-Optics / Infra-Red (EO/IR) range. This helps engineers to improve their simulations of flow field phenomena around fast-moving vehicles and improve the performance of EOIR sensor signals for tracking hypersonic vehicles.
