Sensitivity analysis of three-dimensional salinity simulations in North San Francisco Bay using the unstructured-grid SUNTANS model
Unstructured grid Numerical diffusion Scalar advection scheme Turbulence model Grid resolution
2015/6/30
The unstructured-grid SUNTANS model is applied to San Francisco Bay using a grid with an average resolution of 50 m. This accurately resolves tidal hydrodynamics in a domain that extends from the Paci...

Radiometry photogrammetry digital terrain model radiometric terrain response radiometric calibration block adjustment atmospheric models BRDF
2014/4/24
In this paper we present a radiometric block adjustment method that is related to geometric block adjustment and to the concept of a terrain Digital Radiometric Model (DRM) as a complement to the terr...
Numerical simulation of airfoil flows with a turbulence model
turbulence airfoil incompressible separation openFOAM
2014/5/15
Turbulent flows over AS240 and NACA4412 airfoil were simulated numerically using a two-equation turbulence model named k-ξ model. The predictions of velocity profiles and the pressure coefficient of a...
Heat flux modulation in domino dynamo model
Heat flux modulation domino dynamo model Fluid Dynamics
2012/4/24
Using domino dynamo model we show how variations of the heat flux at the core-mantle boundary change frequency of geomagnetic field reversals. In fact, we are able to demonstrate effect known from the...
Shell model of superfluid turbulence
Shell model superfluid turbulence Kelvin wave cascade phonon emission
2011/8/18
Abstract: Superfluid helium consists of two inter-penetrating fluids, a viscous normal fluid and an inviscid superfluid, coupled by a mutual friction. We develop a two-fluid shell model to study super...

2011/9/2
We combine a simple quasi-geostrophic ow model with the Zabusky-McWilliams theory of atmospheric vortex dynamics to address a hurricanetracking problem of interest to the insurance industry. This enab...
A mathematical model for unsteady mixed flows in closed water pipes
Shallow water equations, unsteady mixed flows, free surface flows, pressurized flows, curvilinear transformation, asymptotic analysis.
2011/9/13
We present the formal derivation of a new unidirectional model for unsteady mixed flows in non uniform closed water pipe. In the case of free surface incompressible flows, the FS-model is formally obt...
Scaling laws prediction from a solvable model of turbulent thermal convection
Turbulent flows, convection and heat transfer Turbulence simulation and modeling
2011/8/31
A solvable turbulent model is used to predict both the structure of the boundary layer and the scaling laws in thermal convection. The transport of heat depends on the interplay between the thermal, v...
