Known Issues 16.0.2
Barracuda VR 16.0.2 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…
Creating high quality movies
The default animation utility in Linux (xanim) is very convenient for viewing animations. In particular, it lets you step forward and backward through the animation, frame-by-frame, which can be very…
Controlling dipleg returns with multiple particle species
In a hypothetical reactor vessel, particles are separated from the gas via cyclones and returned through diplegs. In Barracuda VR, this is typically done through a Pressure BC measuring the…
I can’t view my results in GMV anymore. What can I do?
There are various reasons that GMV output files (named Gmv.#####) may be unreadable by GMV. The three most common reasons are listed below: 1. Filled hard drive. This is more…
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…
Experimental and Theoretical Study of Minimum Fluidization Velocity and Void Fraction of a Limestone Based CO2 Sorbent
Multiphase flow simulations created using Barracuda Virtual Reactor are used to compare with experimental data for determining minimum fluidization velocity for four different sizes of particles.
Avoid Fluidization Pitfalls
Fluidized beds are susceptible to such problems as bed slugging, loss of fines, and gas bypassing. This article explains how to avoid these pitfalls.
Constitutive Equation for Heat Transfer Caused by Mass Transfer
This paper presents a constitutive equation for the thermal heat transfer associated by mass transfer, applicable to both Eulerian–Eulerian and Eulerian–Lagrangian multiphase computational fluid dynamic models.
Introduction to Fluidization
Fluidized beds offer excellent heat transfer, and have the unique ability to move a wide range of solid particles in a fluid-like fashion.
Experimental and CPFD Numerical Study on Hopper Discharge
This study by researchers from the Shanghai Engineering Research Center of Coal Gasification investigated the applicability of the CPFD) numerical scheme for simulating flows in a 3-D hopper.
