TAILIEUCHUNG - On Fsum model and applications

In this paper a 3D model (FSUM) on tidal flows with sediment transport and bed morphology process taking into account the temperature-salinity exchange in estuaries and coastal zones is introduced in more detail. The implicit finite difference method based on semi-Lagrange splitting is used. The software is coded with FORTRAN 90/95. | Vietnam Journal of Mechanics, VAST, Vol. 30, No. 4 (2008), pp. 241 – 251 Special Issue of the 30th Anniversary ON FSUM MODEL AND APPLICATIONS Dang Huu Chung Institute for Mechanics, VAST, Hanoi, Vietnam Abstract. In this paper a 3D model (FSUM) on tidal flows with sediment transport and bed morphology process taking into account the temperature-salinity exchange in estuaries and coastal zones is introduced in more detail. The implicit finite difference method based on semi-Lagrange splitting is used. The software is coded with FORTRAN 90/95. The open boundary condition kinds together source/sink terms are well treated so that it can be applied to every computing domain with the complicated geometry. The software is validated and applied for many different cases and shows the ability of application in practice. 1. INTRODUCTION The significant achievements in Information Technology enable scientists to develop and improve computing software for effectively solving the problems in engineering, especially in computational fluid dynamics. Within the common context of progress the numerical simulation and prediction on tidal flow, sediment transport and coastal bed morphology become feasible and attract many scientists in the world. Although so far there are quite lots of software for this field, self-development is still necessary and plays an important role. It certainly will bring the permanent and practical benefit for scientific progress of the country while the investment is not too expensive in comparison with available trade software. However, this is not an easy work and it always requires efforts and endurance. In this paper FSUM model (tidal Flow, SUbstances transport and Morphology) that was developed and applied for study will be presented in detail. The scope of application is the problems of fluid flows in lake, river, estuary and coastal zone with sediment transport, temperature salinity exchange and bed update due to erosion and deposition .
