| Abstract: | Porous coated cylinders have the potential to reduce the vortex shedding tonal noise as well as broadband noise compared to an uncoated cylinder, although the mechanism of noise reduction is not fully understood. Recent studies show that such benefits can be obtained for both randomised porous coatings as well as structured porous coatings. These coatings have been gaining interest due to their potential application in various fields, such as landing gear struts, wind turbine structures and heat exchangers. The current study presents the first fully resolved Large-Eddy Simulation (LES) of a Structured Porous Coated Cylinder (SPCC). High-fidelity LES data is presented modelling a spanwise section at <i>Re = 73,000</i> (based on outer diameter). Wake profiles of streamwise mean and RMS velocity profiles are presented and compared with an uncoated cylinder and forms a basis to inform and improve Darcy-Forchheimer porous modelling. Boundary layer development on the inner cylinder and shear layer trajectory is also presented. Unsteady data is recorded using a novel solver-independent HDF5-based I/O library developed by Upstream CFD GmbH. |
