The design software system described here is based on a combination of several software components. These components include optimization, physics-based analysis such as computational fluid dynamics (CFD) and finite element analysis (FEA) and supporting tools, and shape design parameterization. The optimization and CFD/FEA related codes, such as mesh generation and partitioning, can be consider...

Windows TM Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of embankment dams. These software components are being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap...

We present two fourth-order compact finite difference (CFD) discretizations of the velocity-pressure formulation of the acoustic wave equation in 2-D rectangular grids. The first method uses standard implicit CFD on nodal meshes and requires solving tridiagonal linear systems along each grid line, while the second scheme employs a novel set of mimetic CFD operators for explicit differentiation ...

nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. it is almost used as a first and the most applicable choice in separation methods. in this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. the study was carried out by using a 3-d...
