WitrynaImpinging velocity Type R. This mode corresponds to low impinging velocities at any surface temperaturesconsidered (200-400 °C). A droplet spreadsas a radial film after impinging on a hot surface. Then, it shrinks and rebounds from the surface without breaking up. Hence, the mode is called R type. [Pg.223] Type H. WitrynaThe geometry of the hemisphere causes the wall jet flow to curve away in all directions, resulting in a relatively thin flow in the light path direction. This allows for a clearer …
WitrynaThe speed outside the boundary layer rises rapidly from 0 at the stagnation point to the impingement velocity in the inviscid far region. For an adhering as well as a slipping jet, the impinging inviscid flow is not affected by slip, and the boundary-layer thickness remains negligibly small. ... and slip velocity (b).
