Avoid Nasty Surprises
Surprises are not always a good thing, especially during plant turnarounds. This article, from the September 2019 issue of Hydrocarbon Engineering, discusses how simulations can be a critical turnaround risk reduction tool.

Simulation of air-biomass gasification in a bubbling fluidized bed using CPFD model
Experiment on the air gasification of biomass in a bubbling fluidized bed reactor was performed in a pilot-scale reactor located at the University of South-Eastern Norway (USN).
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…

CPFD Simulation of Petcoke and SRF Co–Firing In a Full–Scale Cement Calciner
Nakhaei, Wu, Grévain, Jensen, Glarborg, and Dam–Johansen present CPFD simulations for petcoke and solid recovered fuel (SRF) co–firing in a full–scale cement calciner.
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…
