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…
Does Heat from Chemical Reactions Go to the Gas Phase or the Particle Phase?
When chemical reactions are being modelled in the Barracuda Virtual Reactor, it is sometimes important to consider and control where the heat from reactions goes. This post discusses the distribution…
Known Issues 16.0.8
Barracuda VR 16.0.8 Issues fixed in this version: KI-5: Solver crash when Blended Acceleration Model and GPU-mode used KI-6: Flux plane 5-step running average for particle mass flow rate is…
Stopping a Simulation from the Command Line
Barracuda simulations can be stopped using Interact, as long as GUI access is available. In some cases, GUI access is not available, so it is necessary to stop the simulation…
Restarting a Simulation from the Command Line
Restarting a simulation from the command-line can be useful when GUI access is not available, or when writing scripts that run the Barracuda solver. This post describes the steps necessary to…
Adding “Current Directory” to the Linux PATH
Adding the current directory, also known as “.”, to your Linux systems PATH environment variable can make executing scripts more convenient. However, there are some security issues to consider as…
Known Issues 16.0.6
Barracuda VR 16.0.6 Issues affecting this version: KI-1: Particle Drag is not calculated for pure liquid particles when simulation has no solid materials KI-2: 2D data is missing output conversion…
Using Python to Calculate PSDs from Raw Particle Data Files
In Barracuda VR, detailed Particle Size Distribution (PSD) information can be obtained from Raw Particle Data files. There are two ways to generate Raw Particle Data files: When setting up…
Evaporation Model for Droplets and Solid Particle Drying (2024)
Evaporation and particle drying are used in Barracuda Virtual Reactor models for a variety of applications, such as: Coal and biomass gasifiers and combustors (particle drying) Flue gas desulfurization units…
