In this paper. the performance of different wave generation and absorption methods in computational fluid dynamics (CFD)-based numerical wave tanks (NWTs) is analyzed. The open-source CFD code REEF3D is used. which solves the Reynolds-averaged Navier–Stokes (RANS) equations to simulate two-phase flow problems. https://ashleyshomestores.shop/product-category/6-piece-outdoor-seating/
