Impulsive impact of a submerged body

WitrynaTransient Marangoni Waves Due to Impulsive Motion of a Submerged Body Shu, Jian-Jun The Oseen problem in a viscous fluid is formulated for studying the transient free-surface and Marangoni waves generated by the impulsive motion of a submerged body beneath a surface with surfactants. WitrynaWhen high-speed relative motion occurs between the underwater vehicle and the surrounding water, rapid decline in static pressure induces cavity around …

Witryna17 lut 2016 · $\begingroup$ I doubt that a calculation of viscous forces for water is correct for this problem. 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 … WitrynaBecause of the impulse-momentum theorem, we can make a direct connection between how a force acts on an object over time and the motion of the object. One of the reasons why impulse is important … green onion chopping machine

WitrynaIn fluid mechanics, added mass or virtual mass is the inertia added to a system because an accelerating or decelerating body must move (or deflect) some volume of surrounding fluid as it moves through it. Added mass is a common issue because the object and surrounding fluid cannot occupy the same physical space simultaneously.
