RISToward Polydisperse Flows With mfix-exa
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the presence of large size disparities, single-grid neighbor search algorithms lead to inflated neighbor lists that significantly degrade the performance of Lagrangian particle solvers. If Eulerian–Lagrangian (EL) ...
Optimization of a Cyclone Using Multiphase Flow Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The U.S. Department of Energy National Energy Technology Laboratory's (NETL) 50 kWth chemical looping reactor (CLR) has an underperforming cyclone, which was designed using empirical correlations. To improve the performance ...
The Effect of Grid Resolution and Reaction Models in Simulation of a Fluidized Bed Gasifier Through Nonintrusive Uncertainty Quantification Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To improve quality of numerical models used in simulations of a fluidized bed gasifier at any scale, the sources of uncertainty in the simulation have to be identified and quantified. There are several sources of uncertainty ...
