Time-resolved tomographic PIV and pressure measurement of a turbulent shear layer flow impinging on a cavity trailing corner
Abstract
Time-resolved tomographic PIV and pressure measurement of a turbulent shear layer flow impinging on a cavity trailing corner. this proposal presents a research plan aiming to directly measure all components of the pressure-related terms in the context of Reynolds stress budget for a turbulent shear layer flow past a 2D cavity, utilizing time resolved tomographic PIV that couples with a non-intrusive pressure measurement technique. The successful implementation of the plan will not only provide a high quality experimental database consisting of all budget terms in RANS (Reynolds- Averaged Navier Stokes) framework that can be used for computational tools and methods improvement, but also generate a much needed time-resolved surface pressure and pressure temporal derivative distributions over the cavity trailing corner, which can be further utilized for the evaluation of vessel- radiated noise and the development of passive, mitigation strategies. Moreover, the time-resolved 3D experimental data can also be used exploring data assimilation procedures to enhance tomographic PIV measurement resolution.
