Task 5.2 Experimental studies of fluid-structure heat transfer (model combustor). (DLR)

seven people, limousine, marie curie actions

High-amplitude limit-cycle oscillations in the hot fluid cause a thinning of the boundary layers in transient motion, and this enhances the heat transfer from the fluid to the combustor liner. This phenomenon will be studied experimentally from a fundamental perspective in task 5.2. The ESR will be taught to conduct measurements of the transient heat flux to the wall and the transient wall temperature in the model combustor. High-speed thermo-couples and infrared techniques will be used.
