Characterization of flow contributions to drag and lift of a circular
... the Reynolds number (figure 3(b)) to reach a contribution of about 20% of the total drag CD at Re = 400. This evolution is due to an increase of the force density in the back-flow region that is created by the interactions between the shear layers, the vortex roll-up and the cylinder. This intensifi ...

Study of Reaction turbines
... Some fundamental parameters are used to analyze the performance of a pump. The mass flow rate of fluid through the pump, m, is an obvious primary pump performance parameter. For incompressible flow, it is more common to use volume flow rate rather than mass flow rate. In the turbo-machinery industry ...

L↑+ is called the subgroup of proper, orthochronous Lorentz transformations. In the following we will consider solely this subgroup o ...
