An Attempted Extension of a Finite Element Solution to Axisymmetric Potential Flow.

Abstract

A Galerkin finite element method, which has been successfully applied to two-dimensional inviscid flow, has been applied to axisymmetric potential flow. Solutions have been sought for three alternative formulations using different representations for the velocity components. Two of the formulations produced only poor results, while the third gave no worthwhile results at all. Possible reasons for the failure of the method are discussed. (Author)
