| Abstract: | Via a perturbed formulation,the non-homogeneous slightlycompressible condition is introduced into the hybrid functionalin pursuit of the penalty hybrid finite element model for theanalysis of incompressible flow problems.Several types of 8-nodequadrilateral elements are derived,their effectiveness beingnumerically examined. |
