WebWave refraction simulation commencing with deepwater wave height H 0 =1.63 m, and period T =10.64 s. Note the general focusing of energy around the headland where the light patches show wave heights reach 2.5 m, and at various focused sectors further along the coast where waves reach 2.5 m at breaking. Focused wave groups that were smaller in amplitude were generated using linear theory, while for the steepest, but still nonbreaking, waves, a Stokes wave formed by the second-order interaction of the wave components considered was used as input at the source surface at every time step. http://www.tfd.chalmers.se/~hani/kurser/OS_CFD_2024/Eirini_Katsidoniotaki/slides_EiriniKatsidoniotaki.pdf harbor freight 212cc predator engine

Webfocused wave crest as shown in Fig. 4 (b) x=11.66m (WG2) and (c) 12.51 (WG3). When the focused wave crest reaches the maximum height, particle velocity in the upper part of the wave crest increases and thus, kinetic energy. Finally, the steep wave front becomes nearly vertical and eventually the main focused wave crest breaks.
