The Galerkin finite volume method is employed to solve the unsteady incompressible 2D Navier�Stokes equations. The large eddy simulation turbulence model is solved using the artificial compressibility method and dual time-stepping approach. The proposed algorithm is developed for a wide range of turbulent flows with Reynolds numbers of 9500 to 1.5�104. Evaluation of the developed numerical model shows that the proposed technique is capable of properly predicting hydrodynamic forces and simulating the flow pattern. The obtained results show that the lift and drag coefficients are strongly affected by the gap ratio. The mean drag coefficient slightly increases as the gap ratio increases, although the mean lift coefficient rapidly decreases. The vortex shedding suppression happen at the gap ratio of less than 0.2. © 2017, Harbin Engineering University and Springer-Verlag Berlin Heidelberg. date: 2017 publisher: Harbin Engineering University official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85010782706&doi=10.1007%2fs11804-017-1393-y&partnerID=40&md5=5c9d3317d82e6fd4a8a8288bc3fc973a id_number: 10.1007/s11804-017-1393-y full_text_status: none publication: Journal of Marine Science and Application volume: 16 number: 1 pagerange: 81-86 refereed: TRUE issn: 16719433 citation: Namazi-saleh, F. and Kurian, V.J. and Mustaffa, Z. and Tahan, M. and Kim, D.
