Intervenant: Mohammed Seaid (Université de DURHAM ,UK) ----------- Title: Numerical simulation of rotational effects in geophysical flows. ------ Abstract: --------- In many applications in environmental and geophysical flows the time and space scales are mush larger than flows in industrial devices. In this case the dimensionless parameters are much larger and the Earth's rotation plays a significant role in these applications. In this talk we will present new numerical techniques to solve rotational effects in geophysics. The focus on a class of depth- averaged Navier-Stokes equations with hydrostatic pressure. As numerical tools we present a well-balanced finite volume method without Riemann solvers. A projection method is also discussed for the Coriolis force as well as reconstruction of numerical fluxes. Computational results are shown for several geophysical flows.
