Cella A., Gheri G. Spline-blended approximation of Hartmann's flow. In: International Journal for Numerical Methods in Engineering, vol. 8 pp. 529 - 536. Wiley, 1974.
The steady state flow problem known in magnetohydrodynamics as Hartmann's flow is converted into variational formulation and is given an approximate solution by means of the spline blended interpolation technique. The equations of motion consist of two coupled potential flow problems with homogeneous boundary conditions. The spline blended interpolation method is reduced here, because of the shape of the domain, to a cartesian product of cardinal splines with trigonometric or ordinari polynomials. "Exact" boundary conditions are presented by the blending technique. The numerical results indicate that high accuracy is possible with relatively few unknowns.
