WitrynaThe impulsive pressure on the body, the velocity on the free surface, and the associated added mass are determined in a wide range of depths of submergence and for … WitrynaThe results obtained show explicitly the effects of viscosity and surfactants on Kelvin wakes. Keywords: transient Marangoni waves, Kelvin wakes, wavefronts, surfactants 1. Introduction. This study is concerned with the transient surface waves generated by the impulsive motion of a submerged body through an incompressible viscous fluid.

WitrynaRelate impulses to collisions Apply the impulse-momentum theorem to solve problems We have defined momentum to be the product of mass and velocity. Therefore, if an object’s velocity should change (due to the application of a force on the object), then necessarily, its momentum changes as well. WitrynaThe drag on a submerged body can be reduced by injecting micro-bubbles along the boundaries (see section 10.3.3) and by ventilating the aft of the body. Let us consider …
