CE 2200 Chapter : Chapter 4 Flowing Fluids And Pressure Variation Euler
Document Summary
Mass may enter or leave through a control surface. Eulerian: control volume (unchanging shape, but can move, mass may enter or leave through a control surface, open system, fluid particle velocity depends on the point in space and time u tzyxf. Is a line that is everywhere tangent to the velocity at vector at a given instant. Therefore, it has the direction of the velocity vector at each point. Steady flow streamlines are fixed in space. Actual path traveled by a given fluid particle. Locus of particles which have earlier passed through a particular point. Same as pathline and streamline for steady flow. For unsteady flow, the streamline will change with time. The pathline and streakline are generated with the passage of time https://www. youtube. com/watch?v=doufydhxkyq. Viscosity damps any tendency to swirl or mix. Dimensional flow assume constant velocity uniform, axisymmetric velocity distribution.
