INTRODUCTION The objective of this paper is to present a conceptual study of the design of a wave farm composed...

.... In the numerical study, the tuning factor concept is employed, as it explains the relation between the maximum pitch angle and the length of the floating body and wavelength. The relation between tuning factor & pitch period for the generated waves is compared to analyze the effects of wave energy absorption...

... absorption, which is applied to both the inlet and outlet boundary. The result is contrasted with a similar physical model test. It comes out that the calculated pressure generally matches well with the result of model test, which proves this new solver is correct. And the slamming, splash and overtopping...

... Abstract The present investigation concerns optimum wave absorption in numerical wave tanks. Recent developments have now established that (i) absorption controllers based on Infinite Impulse Response (IIR) filters are highly effective and (ii) cosh shaped wave board geometries offer...
