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…
