Develop of a LES/LES-interface for combustor wall cooling.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
This work focusses on the development of a reliable and accurate method to predict the behavior of the wall cooling film and the wall temperature of a gas turbine combustor. Therefore the CFD solver PRECISE-UNS is employed to carry out simulation of the flow in the combustor and is being enhanced to perform locally resolved and numerical efficient Large Eddy Simulation(LES) in the near wall region. Although computational power is increasing, a wall-resolved LES of a gas turbine combustor will still exceed computational resource for the foreseeable future[1]. The objective of the proposed research is hence to implement an efficient embedding technique where the wall region can be treated with the appropriate mesh resolution, whilst a coarse grid can be conveniently adopted in the core flow region.
