The force (drag and lift) exerted on a body moving in a viscous fluid is expressed via the 'free' and 'bound' vorticity moments, and the role of vortex shedding is discussed. The formulation encompasses classical, inviscid flows, and leads to efficient computational methods. Numerical results for a few prototype flows are presented.

Abstract
The force (drag and lift) exerted on a body moving in a viscous fluid is expressed via the 'free' and 'bound' vorticity moments, and the role of vortex shedding is discussed. The formulation encompasses classical, inviscid flows, and leads to efficient computational methods. Numerical results for a few prototype flows are presented.File allegati a questo prodotto
