Simulating Aerothermal Shape Distortion of Hypersonic Vehicles

How can designers of hypersonic aircraft overcome the ‘heat barrier’ using simulation to better understand aerothermal shape distortion (aka aerothermoelasticity, or fluid-structural-thermal interaction - FTSI)? This guest blog by ADFA explains how multiphysics simulation helps designers of hypersonic vehicles account for aerothermal shape distortion (which can compromise a hypersonic vehicle’s aerodynamic performance) through to the risk of catastrophic material failures, using tools that can simulate both the aerodynamics as well as the thermal and structural response.

A look into the lightning-fast future of GPU-powered CFD

Here we benchmark Fluent's new fully-native GPU (Graphics Processing Unit) solver, available since the 2023R1 release, which has delivered impressive numbers on our tests that include both high-end (A100 GPU - over five times faster than a baseline using 80 CPU cores) and standard 8GB GPUs that are probably similar to one you're already using (still delivering a 3x3x speedup over an 8 core Intel Xeon W-11955M CPU).

Heat Exchange CFD Calculations at Conflux Technology

This blog provides highlights from Conflux’s presentation on their CFD heat exchange calculations at the 2021 Australasian Ansys Fluids user group. Learn how a mix of design engineers, simulation experts and additive manufacturing specialists are creating cutting-edge heat transfer solutions with the aim of revolutionising the heat exchange technologies used across many industries.

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.
