Validated, high-speed CFD for industrial jet loop reactors

Rheinland-Pfälzische Technische Universität used Simcenter M-Star to develop and validate a Lattice Boltzmann large-eddy simulation of an industrially relevant jet loop reactor. The simulation reproduced experimentally measured radial velocities and internal circulation flow rates within 8%, while simulating 20 seconds of physical time in less than 54 hours on a single NVIDIA RTX 4090. The study demonstrates Simcenter M-Star’s ability to accurately resolve complex turbulent reactor hydrodynamics while reducing simulation turnaround time by approximately two orders of magnitude compared with representative RANS studies, providing a foundation for rapid optimization and future two-phase reactor modeling.
