Abstract
In order to study the spatial distribution of the flow field, a physical model of the vertical axis tidal current turbine inside the sink is established. Based on the physical model and sliding grid technology, the three dimensional numerical simulation of the flow field is given by using the software Fluent. Both the velocity field on different sections at different moments and the distribution of the velocity and pressure field on different lines at the same moment are analyzed. The result shows that the distribution of the flow field varies at different positions with the impeller rotating in the sink and the change of the flow field will be cyclical under fully developed flow areas. The velocity field is very disordered inside the impellers and the speed changes rapidly around the blades. Under the impeller rotating, vortexes appear. The pressure increases rapidly in the front of the blades facing the flow and decreases to negative pressure rapidly in the back of the blades.关键词
