The mechanisms that control estuarine sediment transport are complicated due to the interaction between riverine flows, tidal currents, waves, and wave-driven currents. In past decade, severe seabed erosion shoreline retreat along sandy coast of western Taiwan have raised concerns regarding sustainability coastal structures. this study, ADCPs (Acoustic Doppler Current Profiler) turbidity meters...

The evolution of the stellar debris after tidal disruption due to the super massive black hole’s tidal force is difficult to solve numerically because of the large dynamical range of the problem. We developed an SPH (Smoothed Particle Hydrodynamics) TVD (Total Variation Diminishing) hybrid code in which the SPH is used to cover a widely spread debris and the TVD is used to compute the stream co...

In this paper, we propose monotonicity preserving and total variation diminishing (TVD) multigrid methods for solving scalar conservation laws. We generalize the upwind-biased residual restriction and interpolation operators for solving linear wave equations to nonlinear conservation laws. The idea is to define nonlinear restriction and interpolation based on localRiemann solutions. Theoretical...

Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...

PURPOSE Metastatic response to induction therapy for high-risk neuroblastoma is a prognostic factor. In the International Society of Paediatric Oncology Europe Neuroblastoma (SIOPEN) HR-NBL-1 protocol, only patients with metastatic complete response (CR) or partial response (PR) with ≤ three abnormal skeletal areas on iodine 123-metaiodobenzylguanidine ([123I]mIBG) scintigraphy and no bone marr...

For system operators, Congestion management is a difficult task as the market’s security and reliability are protected by this methodology. As magnitude of an electric transmission extremely dynamic, limits must be estimated much beforehand, in order to manage congestion issues at right time. Flexible AC systems (FACTS) used control voltage fluctuation adjusting system's real reactive power. A ...

In Xu [11], a class of parametrized flux limiters is developed for high order finite difference/volume essentially non-oscillatory (ENO) and Weighted ENO (WENO) schemes coupled with total variation diminishing (TVD) Runge-Kutta (RK) temporal integration for solving scalar hyperbolic conservation laws to achieve strict maximum principle preserving (MPP). In this paper, we continue along this lin...

The primary aim of the current study is to enhance stability and accuracy Volume-Of-Fluid (VOF) method for modeling free-surface flows with large topological changes high density ratio. For accurate capturing fluid interfaces, a novel higher-order bounded convection scheme first constructed based on total variation diminishing (TVD) concept then employed discretization terms in Navier-Stokes, e...
