On the motion of two cylinders in a fluid
WebEtymology. The English word machine comes through Middle French from Latin machina, which in turn derives from the Greek (Doric μαχανά makhana, Ionic μηχανή mekhane 'contrivance, machine, engine', a derivation from μῆχος mekhos 'means, expedient, remedy'). The word mechanical (Greek: μηχανικός) comes from the same Greek roots.A … Web21 de abr. de 2006 · The two-dimensional motion of a cylinder of fluid released from rest into a flow that is uniform far upstream of the cylinder is studied.
