electrochemistry was a pivotal one, appeared in the sky of science as a new shining phenomenon but they disappeared rather quickly. It was due to either the historical events in Hungary or they did not continue their scientific research at high level because of the low financial support, or just en

Application of Transpiration Cooling for Hot Structures,termined resulting in sample under surface temperature reductions of 50-60%. Altogether, sample under surface temperature reductions of 64% for He, 65% for Ar, 67% for air and 70% for N. were detected. These test series verified that transpiration cooling can be applied successfully for hot structures at application relevant re-entry conditions.

Large Eddy Simulation of Nozzle Jet - External Flow Interaction,edict mean flow quantities in closer agreement with experimental data than the turbulence models. Both prediction methods, however, underline the need to perform fully coupled simulations in order to capture the strong interaction between base and nozzle flow as reliably as possible.

Experimental Study of the Base Flow,asurements and high speed Schlieren visualizations were performed to study the flow topology for cold and warm nozzle flow at several pressure ratios. Among others, the study focuses on the identification of shock oscillations. Recorded spectra provide the dominating oscillation frequencies linked to flow conditions.
