A Numerical Analysis of Casing Groove Parameter on the Performance of Wave Energy Conversion Device
The present computational work has been carried out to comprehend the effect of casing groove width on the performance of the wave energy conversion device. The four different types of groove width to chord ratio is studied such as 0.24, 0.48, 0.64, and 0.96. The circumferential casing groove (CCG) depth (3% of the chord length) and tip (1% of the chord length) clearance are kept constant for all the cases. The fluid analysis was conducted through three-dimensional steady, incompressible, Reynolds-averaged Navier-Stokes (RANS) equations with two-equation eddy viscosity turbulence closer model. The results were compared with different w/C ratio and it is observed that the w/C ratio has a significant impact on the performance. The suitable w/C is 0.64 compared to the others. Furthermore, the comparative study by carried out for different w/C ratio in this study.
