Rese­arch Assist­ant - salary grade E 13 TV-L Ber­liner Hoch­schu­len

As part of the project funded by the DFG "Fundamental Theoretical/Experimental Characterization of Flow Morphology and Local Heat Transfer in Wiped Film Evaporators" (Project Number: 561285967), the flow morphology and its influence on single-phase heat transfer on wiped surfaces of wiped film evaporators (WFE) will be investigated. The project is being conducted in collaboration with TU Braunschweig. At TU Berlin, simulations of fluid dynamics are primarily carried out, while experimental investigations are conducted at TU Braunschweig. The numerical simulations will examine the bow wave geometry as well as the interactions between the film zone and the bow wave, characterizing the mixing between these two zones. Additionally, the single-phase, product-side heat transfer will be simulated. The results will be used to develop a mechanistic model that describes the fluid dynamics and the essential heat transfer in the WFE.

The following specific tasks are to be addressed:

• Development of 2-phase simulation in 3D
• Determination of the interaction between wiper/film
• Determination of the turbulence level
• 2-phase simulation with heat transfer in 3D
