CLAIM

On Using the Delta-Trigonometric Method to Solve the 2-D Neumann Potential Problemion of the second kind. We propose to solve this integral equation using a Petrov-Galerkin method with trigonometric polynomials as test functions, and a span of delta distributions centered at the boundary points as trial functions. For the exterior boundary value problem, the approximate potential

A Study of Flow Structures in a Cavity due to Double-Diffusive Natural Convection by Boundary Elemenand bottom walls. General time dependent results show the development of velocity, temperature and molar fraction fields. Boundary-domain integral method is used and the sub-domain technique combined with block-solver is employed to reduce computer requirements.

Explicit Forms of the Fundamental Solution Tensor and Singular Integrals for the 2D Primitive-Variabprimitive-variable Navier-Stokes boundary element formulation based on the method of Tosaka. Also, explicit forms of singular integrals are derived and presented. In this regard, series expansions of the fundamental solutions, which contain modified Bessel functions, are performed to enable integrat
