Then the design problem with appropriate boundary conditions is solved numerically in stream-function coordinates domain. Next, the geometrical shape of the boundary walls is obtained through the integration along streamlines. The method formulation is described for Cartesian and axisymmetric design ...
Re: Stream Function #3 Jason T. Guest Posts: n/a My total mass flow rate is .68 kg/s. The bottom of the 2d nozzle has a stream line of 0 kg/s and the top has a stream line of ~= .68 kg/s. The point of symmetry has around .34. I did a x-y plot of stream function ...
Then, the foil design problem is considered as an example. Potential applications and developments towards axisymmetric and 3D flows are discussed.doi:10.1007/s00707-013-0841-2M. ButterweckJ.

In three dimensions one refers to a vector potential (not quite the same as a stream function) whose curl is the velocity, and to stream surfaces. A stream line is the intersection of two stream surfaces. In 2D, one of these stream surfaces is simply z=constant, and the remaining stream...
This paper presents a velocity/pressure/function-of-transformation formulation to simulate two- and three-dimensional flows by a finite element Galerkin technique associated to stream-tube analysis. The latter method involves an unknown transformation. Applications are given for plane and axisymmetric flows...

Inverse method for 2D viscous flow design problem using stream-function coordinates for Cartesian and axisymmetric models A new, inverse method for viscous 2D, laminar and turbulent duct flows will be presented. The method is based on incompressible Navier-Stokes equations tra... M Butterweck 被引...
