Cryogenic liquid propellants are used in liquid rocket engines to obtain high specific impulse. The flow rates are controlled by turbopumps that deliver liquid propellant to the engine at high pressure levels. Due to the very low saturation temperatu

In high-pressure single flow Steam Turbines, sealing of the radial gap between rotating and stationary parts in the front end of the turbine is a known design challenge. A traditional solution to control and reduce the leakages between the stationary

Additive manufacturing (AM) enables designs that are not manufacturable with conventional techniques and that offer reduced weight and better thermal performance. This is of particular relevance for gas turbine cooling as well, as proved by the first

It is well known from the literature that surface roughness significantly affects friction and heat transfer. This is even more evident for additive manufactured (AM) components, which are taking an increasingly important role in the gas turbine fiel
