An improved, robust, axial line singularity method for bodies of revolution

7th Applied Aerodynamics Conference, 1989
The failures encountered in attempts to increase the range of applicability of the axial line singularity method for representing incompressible, inviscid flow about an inclined and slender body-of-revolution are presently noted to be common to all efforts to solve Fredholm equations of the first kind.

Scattering by ellipsoids of revolution a comparison of theoretical methods

Journal of Colloid and Interface Science, 1978
Abstract New methods were recently developed for calculating the differential and total scattering cross sections of ellipsoids of revolution. In one, the extended boundary condition method numerically solves Maxwell's equations exactly for this and other particle shapes.

A Method for Generating Phyllotaxis Over Surfaces of Revolution

2022
This paper describes a method for generating phyllotaxis on surfaces of revolution. It extends the work done by previous authors in using Lindenmayer systems (L-systems) to model phyllotaxis in plants for the purposes of generating realistic visual models.

Free vibration analysis of shells of revolution using GDQ method

2006
In this paper, the Generalized Differential Quadrature (GDQ) Method is applied to analyze the dynamical behaviour of double curved shells of revolution. The GDQ method was developed to improve the differential quadrature (DQ) method for the computation of weighting coefficients [1]. It has been found that the GDQ technique can obtain accurate numerical

Fast Analysis of Body-of-Revolution Radomes with Method of Moments

Journal of Electromagnetic Waves and Applications, 2007
By taking advantage of the rotational symmetry, the electromagnetic characteristic of the body of revolution (BOR) radome is fast analyzed by the method of moments (MoM) based on the mode decomposition technique. First, the MoM matrix equation governed by the surface integral is established and the theoretical model is reduced in dimension by using the

Approximate Solutions of Compressible Flows Past Bodies of Revolution by Variational Method

Journal of Applied Mechanics, 1951
Abstract Using the direct method of Rayleigh-Ritz in the calculus of variations, the problem of steady irrotational compressible flow past a body of revolution of arbitrary shape is formulated. In order to compare with the analytical solutions obtained by other investigators, two numerical examples have been carried out, namely ...

Domain decomposition method for scattering from multiple bodies of revolution

2015 IEEE International Conference on Computational Electromagnetics, 2015
In this paper, a domain decomposition method is developed for scattering from multiple conducting bodies of revolution (BoR). The BoR basis functions are utilized to solve the single BoR problem and multilevel fast multipole algorithm (MLFMA) is used to take into account the interaction between multiple BoRs.

Analysis of multicircuit shells of revolution by the field method

Computer Methods in Applied Mechanics and Engineering, 1976
The reported investigation represents a continuation of studies conducted by Cohen (1974). The current analysis treats a much broader class of connected graphs which may contain multiple circuits. Attention is given to the definition of a boundary-value problem, the field relations, a plan of the field method, differential equations for field functions,
