WebUsing cylindrical coordinates, (r,θ,z), where r = 0 is the axis of the axisymmetric flow and (ur,uθ,uz) are the velocities in those (r,θ,z) directions the continuity equation (see … WebStream function is a very useful device in the study of fluid dynamics and was arrived at by the French mathematician Joseph Louis Lagrange in 1781. Of course, it is related to the streamlines of flow, a relationship which we will bring out later. We can define stream functions for both two and three dimensional flows.

Subject - Fluid Mechanics 1 Video Name - Streamline Function and Velocity Potential … In fluid dynamics, the Stokes stream function is used to describe the streamlines and flow velocity in a three-dimensional incompressible flow with axisymmetry. A surface with a constant value of the Stokes stream function encloses a streamtube, everywhere tangential to the flow velocity vectors. Further, the … See more Consider a cylindrical coordinate system ( ρ , φ , z ), with the z–axis the line around which the incompressible flow is axisymmetrical, φ the azimuthal angle and ρ the distance to the z–axis. Then the flow velocity … See more As explained in the general stream function article, definitions using an opposite sign convention – for the relationship between the Stokes stream function and flow velocity – are also in use. See more From calculus it is known that the gradient vector $${\displaystyle \nabla \Psi }$$ is normal to the curve $${\displaystyle \Psi =C}$$ (see … See more In spherical coordinates ( r , θ , φ ), r is the radial distance from the origin, θ is the zenith angle and φ is the azimuthal angle.
