OPTIMAL WIND PROTECTION FENCE THAT MINIMIZE THE SPRAY TRANSPORT TO THE DOWNSTREAM

For decreasing the spray flux by the wave-breaking at the shorelines of the landward area, the optimal wind protection fence structure was discussed experimentally and numerically. For minimizing the salt-spray flux through the fence, a structure with two staggered rows of circular cylinders with different spaces between cylinders is selected and wind tunnel experiments have been conducted. The salt spray amount deposited and passed through the wind fence were measured. The spray volume getting through or blowing up the fence was quantified by colored water with dye. The water was sprayed with a sprayer at wind fence upstream and collected by gauzes placed at downstream points. For the subsidence volume at the downstream bottom, a tray was put and the mass of the subsiding water was measured. A 2D model (RANS Reynolds-Averaged Navier-Stokes equations) using k-ε turbulence closure model is used to simulate the velocity field and the distribution of the spray concentration behind the fence. Considering the loss of the spray that blows upward the fence, the (1D-2D) staggered circular cylinders arrangement is the best one to use.
