Wilde Analysis partnered with IAC Acoustics to evaluate the effectiveness of an engine Ground Run-Up Enclosure (GRE) for the Airbus A320 series aircraft at airports located in Prague and Hamburg.
The GRE was analysed under different wind conditions and engine thrusts to comment on the environmental impact of the jet exhaust, in terms of plume trajectory and acoustic noise.
Furthermore, regions of turbulence and recirculation were identified within the GRE to minimize the probability of hot air re-ingestion within the engine intakes.
Using ANSYS CFX-Pre for boundary condition set-up alongside ANSYS DesignModeler for geometric revisions, the project was easily parameterised within the ANSYS Workbench platform.
Results obtained from the simulations showed that the regions of turbulence were marginal within the GRE. Outside the GRE the exhaust was successfully deflected upwards and away from regions of concern.
IAC and Wilde Analysis have been working together for several years now, and we at IAC know that our CFD and FEA work is in safe hands. The intuitive way the work is completed means IAC engineers can be confident of high-quality results delivered by Wilde on schedule.
