Abstract Well-resolved Large-Eddy Simulations (LES) of a pseudo-shock system in the
divergent part of a Laval nozzle with rectangular cross section are conducted and compared …

During previous investigations on pseudo-shock systems, we have observed reproducible
differences between measurement and simulations for the pressure distribution as well as …

The interaction between a normal shock wave and a boundary layer along a wall surface in
internal compressible flows causes a very complicated flow. This interaction region …

Introduction Within the joint project PAK 75 (Deutsche Forschungsgesellschaft DFG), a novel
process for the production of gas phase synthesized particles is developed. The key features …

Introduction The acceleration of a fluid in a Laval nozzle to supersonic speed leads to a
significant decrease of the static temperature in the flow, and deceleration via a normal …

The flow conditions in Laval nozzles (convergent-divergent nozzle geometry) are defined by
the pressure ratio between inlet and outlet. If this ratio is sufficiently high, the flow is …

A pseudo-shock system in a rectangular nozzle with parallel side walls is investigated at
different pre-shock Mach numbers by means of wall pressure measurements and high …

Within the scope of this work, we investigate the potential of passive flow control of pseudo-
shock systems via bypass mass flow through longitudinal gaps. We show that within a …

The interaction between a normal shock wave and a boundary layer in the internal
compressible flow is a very complicated flow. The interaction region containing shock train …
