WitrynaHancock, the No. 6 pick in the 2024 Draft, continues to distance himself from the early-career injuries that were setbacks to his path to the Majors. He was twice shut down in 2024 with a right shoulder impingement, and in ‘22, a strained lat muscle delayed his debut until mid-May. Staying healthy has been his paramount priority since. Witryna24 cze 2024 · A droplet in oblique impact is subject to a combination of downward motion along the surface with a tangential impinging velocity of v 0 sinϕ and motion normal to the surface with an impinging velocity of v 0 cosϕ, where v 0 is the impact velocity and ϕ is the tilt angle of the surface. The downward motion promotes the drop to move … Witryna17 mar 2024 · Furthermore, the detailed jet impingement, velocity, pressure, vorticity, and turbulence fields during wave breaking are discussed and presented, providing more detailed flow fields to gain further insight into the plunging jet and splash-up in shallow-water breaking waves.
