This paper investigates the influence of time step setting on the CFD simulation result of vertical axis tidal current turbine. Two main features of time step setting have been studied. The first feature concerns with time step size setting that representing the detailed calculation on each degree in one turbine rotation. The second feature deals with number of time step setting that representing how many turbine rotations need for achieving steadiness results. In this study, two-dimensional (2D) analysis of Computational Fluid Dynamics (CFD) simulation using ANSYS-Fluent code with Sliding Mesh technique is used to solve the incompressible Unsteady ReynoldsAveraged Navier-Stokes equations. The finite volume discretization method with second-order scheme and the SIMPLE algorithm are used for all transport equations. The steadiness calculation result is achieved at six turbine rotations and the rest has no significant effect.
