Abstract: | The authors developed a method to adequately compute the fluid-structure interactions to analyze a coupled phenomena for
gas, liquid and solid. With the implementation of VOF method, the new methodology may handle the moving boundaries as well.
The present technique is based on the predecessing approach for analyzing the incompressible viscous fluid for large scale
problems 3]. The characteristic of this method is that by implementing the matrix-storage free formulation 1], which is
based on the one-point quadrature scheme, the amount of necessary storage and the number of operations for calculating the
integration are considerably. Moreover, the data-parallel coding is implemented taking advantage of the element-by-element
structure of the program. We selected two problems in order to examine the effectiveness of this newly developed program:flow
inside a subway station and water scour around a bridge pier. |
