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).

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.

CFD Modelling of Biological methanation in bubble column reactors

Read how the advanced multiphase capabilities of Ansys Fluent (combining hydrodynamics with mass transfer and chemical reaction) are being used to model 3D bioreactors and used as inputs to validate simpler 1D models suitable for process design and optimisation using simpler, computationally faster models.

Behind the scenes of how Emirates Team New Zealand sailed to new wind-powered land speed record

The engineering behind the scenes of Horonuku – the successful attempt by ETNZ to break the wind-powered land speed record, drawing upon experience from engineers across ETNZ whose careers have focused on the complex physics of aerodynamics, dynamics, structural mechanics and composite materials.

Guest blog by FCT Combustion: How CFD helps develop tailored burner designs for Alternative Fuels

Guest Blog highlighting the use of CFD on a real-world burner optimisation project that allowed FCT’s client to increase their use of alternative fuels while solving an issue of costly shutdowns due to kiln build-up. CFD also enabled implementation of a new burner design that improves clinker quality and production.
