High-Order Overset-Grid Simulations of Acoustic Scattering from Multiple CylindersA parallel, overset-grid method based on high-order spatial and temporal algorithms is used to solve the multiple-body acoustic scattering problems associated with Category 2 of the Fourth Computational Aeroacoustics Workshop on Benchmark Problems. The solution methodology is based on a spatially high-order compact finite-difference algorithm coupled with high-order, low-pass spatial filtering. Various parametric studies are performed to evaluate the accuracy of the computational algorithm.
