A Clausius-Rankine-cycle has been proposed to recover waste heat from a piston engine. This waste heat is then used to supercharge the cylinders by means of a steam turbocharger. The advantage of using this steam turbocharger ...

Steady RANS simulations form the backbone of the aerodynamic turbomachinery design tool chain. They combine a fast response with the ability to describe three-dimensional geometries. However, they are based on approximations ...

Um den wirtschaftlichen und klimapolitischen Zielen bei der Weiterentwicklung von axialen Strömungsmaschinen Rechnung zu tragen, sind die Hersteller aufgefordert, deren Leistungsdichte zu erhöhen. Dies kann durch eine ...

A numerical modelling chain is presented in this thesis, with the aim of improving the reproduction of the influence of realistic boundary conditions on the aerothermodynamics of low-pressure turbine blades. After an ...

Diffusers increase the power output and cycle efficiency of gas turbines by reducing the back pressure of the turbine, thus, increasing the work extracted from the fluid by the turbine. They are, however, challenging to ...
