Simulation of Tidal Stream Turbine Working Near Free Surface Junwei Zhoua and Dazheng Wang School of Naval Architecture and Ocean Engineering, Harbin Institute of Technology in Weihai, Weihai 264209, China azhou_junwei@foxmail.com Keywords: tidal stream turbine, free surface, immersion depth, wave Abstract.
Turbine simulation with wave Numerial method.
The CFD method was validated by Myers’s experimental result.
The wave shape was compared with turbines of the same scale, immersion depth, inflow velocity and thrust coefficient, while the water region of the CFD is deeper and wider.
Since the simulation based on a similar geometry, the difference of the two conditions is not caused by parameter of D.

Consequently, the normalised RMSE errors for the two chemical equations reaction rates top 100% and building a reduced order model was not feasible based on the available CFD data.
The turbulence model used is the detached eddy simulation model (DES) [11].
The boundary conditions were the same as in the previous simulation [8].
The simulation can be performed either with a commercial or in-house code.
Consequently, the still large errors in the reconstruction of some of the variables (vorticity, CO mass fraction and shear strain rate), a reduced order model is not yet feasible based on the available CFD data.

However, the roll stiffness of the aerostatic bearing has seldom been studied, partly due to the difficulty in accurate simulation of the pressure distribution in non-isopachous thin gas film.
The pressure distribution of the aerostatic bearing is numerically solved by using the computational fluid dynamics (CFD) software Fluent.
The relationship between the pressure distribution p and the air gap h solved by using the CFD software Fluent is shown in Fig. 3.
Since the pressure distribution p is solved numerically by using CFD software Fluent, the normal stiffness and the roll stiffness of the entire planar aerostatic bearing in can be rewritten by using the numerical results as follows (10) (11) whereis the pressure at the position with radius.

Present study deals with 3-dimensional transient numerical simulations of the IIC structure for high performance turbine.
Cooling performance of four newly proposed IIC configurations along with two configurations by Funazaki and Hamidon (2008) have been investigated using k-ε turbulence model via commercial CFD package, Ansys Fluent.
