摘要

The GPU CABARET method solver is further optimised for conducting industrially relevant acoustic sensitive LES calculations on GPU cards in the computer-under-the-desk mode. The solver is combined with an efficient implementation of the Ffowcs Williams -Hawkings (FW-H) penetrable surface method which allows on-the-fly computations of acoustic integrands within a flexibly wide range of acoustic surfaces to accommodate the sensitivity of the FW-H method to the grid resolution and flow details at a moderate computational cost The grid sensitivity study has been performed for the static and coflow, isothermal and heated jet cases from the recent SILOET experiment on several LES grids. The flow solutions are compared with the reference RANS/LES calculations of Tucker et al (2014). Acoustic spectra predictions are obtained and compared with the experiment in each case.
