Tail flow on a stepped cylinder with exhaust plume (TRR40)
Tail flow on a stepped cylinder with exhaust plume (TRR40)
Precise characterisation of transient flow processes around the tail section is particularly relevant for the design and assessment of future space transport vehicles. The complex interaction between chemical processes and a turbulent flow field significantly affects the thermal and aerodynamic stresses acting on the launcher. Scale-adapted simulations are conducted on generic models at the DLR Institute of Aerodynamics and Flow Technology in order to quantify these effects with a high degree of reliability and precision. The image is an example of the results obtained from this kind of simulation, which was performed as part of the SFB-TRR40 project by the German Research Foundation (DFG).
