We report direct numerical simulations of a synthetic jet issuing in a quiescent environment performed by two widespread open-source computational fuid dynamics (CFD) codes: Nek5000 and the OpenFOAM solver pimpleFoam. While the former employs a high-order spectral-element method, the latter is based on finite-volume, lower- order schemes. The flow parameters are based on the experimental data of Yao et al. (2006). The performances of the two codes are compared thoroughly, with regard to accuracy as well as computational cost. Our computations show that Nek5000 is globally more efficient than pimpleFoam for the problem under study.

Abstract
We report direct numerical simulations of a synthetic jet issuing in a quiescent environment performed by two widespread open-source computational fuid dynamics (CFD) codes: Nek5000 and the OpenFOAM solver pimpleFoam. While the former employs a high-order spectral-element method, the latter is based on finite-volume, lower- order schemes. The flow parameters are based on the experimental data of Yao et al. (2006). The performances of the two codes are compared thoroughly, with regard to accuracy as well as computational cost. Our computations show that Nek5000 is globally more efficient than pimpleFoam for the problem under study.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
