Cylindrical stream function
WebFeb 12, 2024 · I have made this plot of streamlines around a cylinder with a radius of 1. Is there a way to remove whats inside the cylinder and maybe even high lite the cylinder with a different colour? WebApr 12, 2024 · Bochkarev [ 12] decided to study the aerothermoelastic characteristics of a loaded functionally graded circular cylindrical shell under the action of supersonic airflow. The influence of the different combination of mechanical, thermal and aerodynamic loads on the stability of the structure was analyzed.

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. In axisymmetric flow, with θ = 0 the rotational symmetry … See more In cylindrical coordinates, the divergence of the velocity field u becomes: as expected for an incompressible flow. And in spherical coordinates: See more
