Solving Conjugate Heat Transfer problems

  For many simulations of real world engineering applications, the predictions of heat transfer properties are as important, if not more important, than the actual flow field. Such scenarios include simulations of heat exchangers, HVAC (Heating, Ventilation and Air Conditioning), combustion/burners, electronics cooling, and many more. In these applications, we are often interested in how heat...

Sunswift leads race to Adelaide in new "Cruiser" class of 2013 World Solar Challenge

In the past, posters of cars such as the KTM Crossbow and Infiniti Red Bull F1 would adorn the bedroom walls of teenagers who were passionate about motorsport, while solar cars were banished to science fairs as a mere curiosity. Enter the UNSW Sunswift Solar Car Team, who are looking to radically change this status...

Turbulence Part 5 - Overview of Scale-Resolving Simulations (SRS)

An increasing number of industrial CFD users are recognising the need to move away from RANS modelling and resolve a greater spectrum of turbulence (particularly in cases involving large-scale separation, strongly swirling flows, acoustics, etc.). Here we present an overview of Scale Resolving Simulation techniques and important considerations when considering applying SRS to your project.

CFD keeps Emirates Team New Zealand on course to reclaim the America's Cup

LEAP staff, in particular our team of CFD engineers, have been watching with interest as the 2013 America's Cup unfolds in San Francisco. Despite being the oldest active trophy in international sport, the America's Cup is continually evolving thanks to an often dramatic combination of ...

Turbulence Part 4 - Reviewing how well you have resolved the Boundary Layer

In recent posts we have comprehensively discussed inflation meshing requirements for resolving or modeling wall-bounded flow effects due to the turbulent boundary layer. We have identified the y-plus value as the critical parameter for inflation meshing requirements, since it allows us to determine whether our first cell resides within the laminar sub-layer, or the logarithmic...
