Titel und Abstract des Dissertationsprojektes
Experimental and Computational Investigation of Convective Heat Transfer on Rough Surfaces
To achieve a better understanding of the flow and heat transfer processes along an additively manufactured rough surface, their accurate computational prediction is needed. The majority of the existing wall-function based roughness models have been used and validated mainly for hydrodynamic problem i.e. for the momentum transfer processes, but not necessarily for thermal problem, i.e. for the convective heat transfer in the existence of a temperature gradient. Thus, for accurate heat transfer predictions, a further validation, assessment and improvement of the models is necessary. The proposed research consists of two main work as experimental and computational. While in the experimental side a test rig is designed and data are collected with different roughness patterns, the results are compared with computational model for validation. Furthermore, the computational model is enhanced and developed to reach a wide range of roughness pattern and to obtain better accuracy for prediction of flow and heat transfer behavior.
