Barracuda Hardware Timing Problem
A standard hardware timing problem has been created and made available to all Barracuda Virtual Reactor customers. It is intended to provide useful information about the fastest available hardware (both…
Particle Segregation in Barracuda
Particle segregation in Barracuda Virtual Reactor® is influenced by both fundamentals and empirical models. Barracuda Virtual Reactor results can range from full particle segregation to uniform beds depending on the…
Custom EMMS Drag Model Multiplier Tables
Proper selection of the drag model can have a significant effect on the results from Barracuda Virtual Reactor simulations. As part of our continuing study of drag models, CPFD Software,…
Things to consider when simulating cyclones
Many cyclones have been run successfully with the Barracuda Virtual Reactor. However cyclones, and other swirl devices, present unique numerical and modeling challenges, which can be different from those in…
Setting particle-to-wall interaction parameters
Particle-to-wall interaction parameters are specified in the Barracuda Virtual Reactor GUI on the Particles window. The values of these three parameters – normal-to-wall momentum retention, tangent-to-wall momentum retention, and diffuse bounce – can have…
Setting the Basis (Mass Flow Rate or Velocity) for a Flow BC
When editing a Flow file for a Flow BC in Barracuda, you can double-click on the header of the Velocity / Mass Flow Rate column. When the Select… dialog pops…
Fluid to Particle Heat Transfer in Barracuda
Heat transfer between a particle and the surrounding fluid is calculated using a correlation for the Nusselt number in Barracuda. While default correlation values are provided in Barracuda, there may…
How do I set wall erosion parameters for my unit?
Surface erosion is dependent upon many factors including surface material, particle material, particle shape, quality of surface installation, time in service, temperature, chemistry and certainly much more. A comprehensive model…
Understanding nvidia-smi GPU usage information
When running Virtual Reactor with GPU parallel acceleration, the nvidia-smi command-line tool is useful for monitoring the memory usage, temperature, and number of processes using the GPU card(s) on your system.…
