The person will be initially moving at 40 m/s, so entry into the water should produce turbulent flow around the person. If you know the drag coefficient for the person, you should be able to set this up as a fluid drag problem, where the drag …

"Witryna1. When a circular cylinder is submerged in a uniform stream, the surface elevation may be calculated, to a first approximation, by a method due originally to Lamb for this case, and later extended to bodies of more general form: the method consists in replacing the cylinder by the equivalent doublet at its centre and then finding the fluid motion due to … " - Impulsive impact of a submerged body

Witryna5 lut 2024 · Experimental studies of supercavitating models moving at speeds in the range from 400 m/s to 1000 m/s revealed a regime of bouncing motion, in which the rear part of an axisymmetric body periodically bounces against the free boundaries of the supercavity. The impulsive force generated by the impacts is the main concern in this … Witrynato study the transient interaction of impulsive motion of a submerged body with a contaminated surface, and the consequence in terms of transient Marangoni waves. …

Witryna1 lis 2024 · The model of Milder (1974) modified by considering viscous and drag force effects achieved results consistent with the experimental results. A modified model was proposed with a free surface assumption and exhibited critical fluid physics of the surface waves generated by a submerged body in the stratified fluid (Li et al., 2024). When … WitrynaAn analytical solution of the impulsive impact of a cylindrical body submerged below a calm water surface is obtained by solving a free boundary problem. The shape of the cross-section of the body is arbitrary. The integral hodograph method is applied to derive the complex velocity potential deﬁned in a parameter plane. The boundary-value …

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.
