Researchers show mechanics of how drag on a partially submerged object may be several times greater than drag on a fully submerged object made of the same material. One of the most common and ...

One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing it to a steady flow to measure its ...

In a first part 1, denoted (I), the authors had presented a semi-analytical approximate solution to the problem of multiple scattering of an incident harmonic wave by a finite number of obstacles ...

Piling up: this image shows water flowing from left to right past a partially submerged sphere. A pile up of water is clearly seen to the immediate left of the sphere. (Courtesy: Harris Lab) ...
