When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of fluid through a duct ...

Velocity is always TANGENT to the path. Acceleration, in general, has BOTH tangential and normal components. The normal component of acceleration always points INWARD to the path. The tangential ...

As expected, the acceleration of P has both non-zero tangential and normal components. From the equation provided for speed as a function of distance traveled, the speed of P is monotonically ...

This is a preview. Log in through your library . Abstract A flow model is presented that predicts the swirl and turbulent velocities in an open chamber, cup-in-piston I. C. engine. The swirl model is ...
