    Dual Flow Deflector casing for cross-flow wind turbine was proposed to get higher performance of the wind turbine. This casing is composed of two flow deflector plates. For cross-flow wind turbine, it has an undesirable part of swept area where the blades travel in the opposite direction to the wind, so the wind slows down the turbine rotor rotation. Therefore one of the two flow deflector plates is located in front of this part of swept area to block the wind from entering. And another flow deflector plate with some angle of attack is located nearby where the blades travel in the same direction of the wind. This plate generates accelerated flow to assist the rotation of the turbine rotor. In this study, 2D numerical flow analyses of cross-flow wind turbine with Dual Flow Deflector casing were carried out, by using OpenFOAM (open source CFD software package). The results of the numerical analyses were evaluated by comparing the flow field and performance of the wind turbine with the experimental results.

    A model for joint probability distribution of wind and wave is proposed and relations between wind speed, wave height and wave period at deep water near the Choshi offshore wind demonstration site are derived by using 10 years simulation data, which are obtained from mesoscale and third generation wave models. Mean values, standard deviations, probability distributions of wave height and wave period are expressed as functions of wind speeds and modeled by combined models of wind wave and swell, linear functions and log-normal distributions, respectively. The correlation coefficient between wave height and wave period is also modeled as a function of wind and expressed by a hyperbolic tangent function. Monte Carlo simulation is conducted, and wind speeds, wave heights and wave periods are generated based on proposed models. Predicted joint probability distributions show satisfactory agreement with observations.
