Guest Blog by Wood Australia: Transient CFD analysis of cooldown of Subsea Christmas Tree

Guest Blog by Wood Australia. Edward Yap, CFD Consultant and Deepak Jagannatha, Lead CFD Consultant, recently presented this in-depth look at their analysis of a Subsea Christmas Tree, commonly used in the Oil and Gas industry, as part of LEAP’s Ansys CFD Virtual User Group meeting.

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.

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.

Guest Blog by RayGen: Powering a renewable energy future with simulation

RayGen explains their vision to accelerate the global transition to renewable energy and how they are using CFD simulation to deliver innovative solar infrastructure projects such as their unique ‘PV Ultra’ concentrated PV technology that provides dispatchable electricity, heat, cooling and desalinated water, all day and night.
