A chebyshev spectral collocation method for the computation of buoyancy-induced flows
Karageorghis, Andreas; Sivaloganathan, S. (1993)A spectral/Powell-hybrid algorithm is presented for the solution of the Boussinesq equations. The method is applied to a streamfunction formulation of the governing equations and used to solve the "double-glazing" test ...

Conforming spectral approximations for non-conforming domain decompositions
Karageorghis, Andreas; Sivaloganathan, S. (1998)A spectral domain decomposition scheme is introduced for the numerical solution of second- and fourth-order elliptic problems. The technique is applicable to certain domain decompositions of rectangular or rectangularly ...

Numerical solution of the 3-D buoyancy driven cavity problem by a pseudospectral method
Sivaloganathan, S.; Karageorghis, Andreas (1996)The pseudospectral continuation technique introduced in Karageorghis and Sivaloganathan for 2-D recirculating flows is extended to three dimensions. The pseudospectral/continuation strategy is applied to the vorticity/vector ...
