Effect of roughness on tip vortex rollup and instabilities in narrow gaps

Abstract

This project aims to explore the effect of roughness on tip leakage and trailing edge vortices in tip gap flows and the subsequent instabilities between the two vortices. Specifically, we will aim to explore how roughness can control and even mitigate these effects through a thorough testing of the parameters space. This will require very sensitive and distributed velocity measurements to have unprecedented detectability limits to assess the sensitivity of the input parameters on the flow structures. We aim to accomplish this improvement in detectability by further developing our molecular tagging velocimetry techniques and implementing new data processing techniques, including machine learning based strategies.APPROVED FOR PUBLIC RELEASE
