Computational Fluid Dynamics Validation Study of Wake-Capturing Capability for Flat-Plate Wake

摘要

This paper studies a computational uid dynamics validation study ofwake-capturing capability for unsteady owncharacteristics. The computational fluid dynamics code used in this study is based on the Cartesian grid systemwithnoctree mesh refinement and uses a weighted essentially nonoscillatory numerical scheme to achieve higher-ordernaccuracy to preserve unsteady flow characteristics. Flow properties in the flat-plate wake flowfield, such as meannvelocity, rootmean square of perturbation velocity, and frequencywise power spectrumof flowvelocity,were chosenno validate the computational fluid dynamics code. The comparison between computational fluid dynamics resultsnand experimental data showed good agreement for mean velocity and low-frequency fluctuations.
