Lin, Cosman, Heemink, Stijnen, van Beek: Parallelization of the Particle Model SIMPAR
Particle methods are an important technique for simulating transport phenomena such as the transport of pollutants in coastal waters. Particle methods can quite accurately predict the pollutant transport in cases of steep concentration gradients after the pollutant has just entered into the water, whereas conventional numerical methods such as finite difference and finite volume methods may hav...
متن کاملFinite-Volume-Particle Methods for Models of Transport of Pollutant in Shallow Water
We present a new hybrid numerical method for computing the transport of a passive pollutant by a flow. The flow is modeled by the Saint-Venant system of shallow water equations and the pollutant propagation is described by a transport equation. The idea behind the new finite-volume-particle (FVP) method is to use different schemes for the flow and the pollution computations: the shallow water e...
متن کاملOn a Hybrid Finite-volume-particle Method
We present a hybrid finite-volume-particle numerical method for computing the transport of a passive pollutant by a flow. The flow is modeled by the oneand two-dimensional Saint-Venant system of shallow water equations and the pollutant propagation is described by a transport equation. This paper is an extension of our previous work [Chertock, Kurganov and Petrova, J. Sci. Comput. (to appear)],...
متن کاملPropagation of Diffusing Pollutant by a Hybrid Eulerian-Lagrangian Method
We present a hybrid numerical method for computing the propagation of a diffusing passive pollutant in shallow water. The flow is modeled by the SaintVenant system of shallow water equations and the pollutant propagation is described by a convection-diffusion equation. In this paper, we extend the hybrid finite-volume-particle (FVP) method, which was originally introduced in [CK04, CKP06] for t...
متن کاملCharacterisation of the interaction between a boundary layer and a cavity using Digital Particle Velocimetry with Optical Flow
An Optical Flow technique based on the use of Dynamic Programming has been applied to Particle Image Velocimetry yielding a significant increase in the accuracy and spatial resolution of the velocity field. Results are presented for an interaction between a laminar boundary layer and a cavity. The experimental characterisation of the interaction between a boundary layer and a cavity was develop...
