Experimental Characterization of Axisymmetric Base Flows with Propulsive Jet (B04)

Subject Area Fluid Mechanics
Term from 2008 to 2020
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 26293245
 

Project Description

The project provides experimental simulation of supersonic afterbody flows with high-speed propulsive jets. This allows characterizing the aerodynamic interactions of dual-bell nozzles with the external flow around an axisymmetric afterbody. Time-resolving pressure measurements will be used to describe aerodynamic loads, while the results of hot-wire anemometry and PIV will characterize velocity fluctuations and turbulent transport. The robustness of passive flow control means is assessed by varying Mach number, angle of attack and nozzle flow parameters.
