Abstract

Historically, computational fluid dynamic (CFD) simulations in the aerospace and energy industries have relied on steady Reynolds-Averaged Navier-Stokes (RANS) approaches. Transient Scale-Resolving Simulations (SRS) produce much more accurate results for unsteady fluid flows, but their high computational cost and complex setup procedures have limited their application within industrial design cycles. However, the lattice-Bolzmann method (LBM) solver SIMULIA PowerFLOW's explicit scheme and straightforward setup procedures enable rapid simulation turnaround time for even complex geometries. For the past five years, Techsburg has used PowerFLOW® to tackle some of the most challenging problems in the aerospace and energy industries. From predicting the community noise of emerging aircraft concepts such as Advanced Air Mobility (AAM), electric ducted fans, and truss-braced wing airliners to optimizing the efficiency of the next generation of gas turbines for aircraft propulsion and power generation, PowerFLOW® has proven to be an efficient and robust tool for high-fidelity aerodynamic/aeroacoustic simulations.

Presenter Bio

Matthew Langford, Chief Engineer, Techsburg, Inc.

Matt Langford is the Chief Engineer at Techsburg, Inc. (located in Christiansburg VA), where he has worked since 2003. His technical focus over that time has been on aerodynamics and aeroacoustics of aircraft propulsion systems, including fans, propellers, vertical lift, and gas turbines. He has split time between experimental and computational projects, but efforts since 2020 have focused on unsteady computational fluid dynamics and computational aeroacoustics using the SIMULIA PowerFLOW® lattice-Boltzmann method solver.
