Ongoing research focuses on development of cooling channel designs for an effective cooling of the plasma-faced First Wall (FW) of the DEMO fusion power reactor. Structuring the fluid-solid-interfaces by rib-elements as turbulence promoters is an appropriate method for increasing the thermal performance of gas-cooled heat-exchanger components.
Promising design concepts facilitate:
(a) a reduction of the maximum wall temperatures,
(b) a decrease of the wall temperatures gradients,
(c) an increase the mean coolant temperature, and
(d) cost-efficient manufacturing.
The objective of the master thesis is the numerical simulation of turbulent flow and heat transfer in cooling channels of the first wall with structured surfaces. Computations will be conducted by Detached-Eddy-Simulation (DES).
The work includes:
- Short Literature review.
- Numerical grid generation.
- DES simulations and analysing the results.
- Writing the master thesis and presentation the results within a scientific colloquium.
