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.

Exploring new ideas in Urban Design – a Q&A with Wendy Walls, Melbourne School of Design

Q&A with Wendy Walls whose research and teaching aims to deliver innovative design methodologies for urban open spaces, designed in response to a changing climate. Learn how Wendy's use of Ansys Discovery has provided an engaging way to teach landscape design students the critical concepts involving airflow and heat transfer in urban design.

Guest Blog by Prof. David Fletcher: Importance of following Best Practices for Scale Resolving Turbulence Modelling

Guest Blog explaining the significance of the new Stress-Blended Eddy Simulation (SBES) turbulence approach which makes use of the best available models for both near-wall and far field accuracy, within one single scale-resolving CFD simulation, including a recording of highlights from our recent webinar.

Guest Blog by ANU Rocketry: Democratisation of Space starts with university student teams

Founded in 2018 to participate in the Australian Universities Rocket Competition (AURC), students from the Australian National University’s (ANU) Rocketry team are striving to develop a rocket capable of passing the boundary of outer space and being safely recovered by parachute upon re-entry. This lofty goal has led the team to move away from commercially available solid-fuel propelled rockets to develop their own in-house designed bipropellant liquid-fuel engine, with the help of Ansys aerothermal analysis to predict the heat flux at the space rocket’s leading edges during its hypersonic ascent phase.

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.
