三亚国际数学论坛 Modeling Analysis Simulations Applications Inter-Facial Dynamics and FSI Problems
2017/11/24
The focus of the workshop will be on mathematical modeling and analysis of interface dynamics problems, and fluid interaction problems, the theory and analysis of the related partial differential equa...
On the physical accuracy of scalar transport modeling in inhomogeneous turbulence
physical accuracy scalar transport modeling inhomogeneous turbulence
2016/5/18
Direct numerical simulations of scalar fields produced by uniform and line sources in channel flow are used as the basis for examining the accuracy of random flight and closure models in predicting tu...
Factor of safety in a partially saturated slope inferred from hydro-mechanical continuum modeling
partially saturated soil hydromechanical model slope stability
2015/7/1
Rainfall weakens an earth slope and triggers mass movement. Relevant triggering mechanisms are complex and include reduction of capillary pressure due to increased saturation and frictional drag on th...
Modeling the tidal and sub-tidal hydrodynamics in a shallow, micro-tidal estuary
Estuaries Galveston Bay Unstructured grid Surface heat flux SUNTANS
2015/6/30
The three-dimensional hydrodynamics of Galveston Bay were simulated in two periods of several month duration. The physical setting of Galveston Bay is described by synthesis of long-term observations....
Analytical modeling for the heat transfer in sheared flows of nanofluids
Analytical modeling heat transfer sheared flows of nanofluids Fluid Dynamics
2012/4/24
We developed a model for the enhancement of the heat flux by spherical and elongated nano- particles in sheared laminar flows of nano-fluids. Besides the heat flux carried by the nanoparticles the mod...
Surrogate-based modeling and dimension reduction techniques for multi-scale mechanics problems
Multi-scale mechanics Cryogenic cavitating flow Surrogate-based modeling Active flow control Engineering system
2012/2/28
Successful modeling and/or design of engineering systems often requires one to address the impact of multiple “design variables” on the prescribed outcome. There are often multiple, competing objectiv...
Modeling the transition to turbulence in shear flows
Modeling transition turbulence shear flows
2011/8/5
Abstract: One-dimensional models are presented for transitional shear flows. The models have two variables corresponding to turbulence intensity and mean shear. These variables evolve according to sim...
Unsteady aerodynamics modeling for flight dynamics application
Unsteady aerodynamics High angle of attack Mathematical model Flight dynamics Bifurcation analysis Post-stall maneuver
2012/2/24
In view of engineering application, it is practicable to decompose the aerodynamics into three components: the static aerodynamics, the aerodynamic increment due to steady rotations, and the aerodynam...
A quadratic Petrov-Galerkin formulation for advection-diffusion-reaction problems in turbulence modeling
reaction effects stabilized finite element method turbulence modelling
2010/3/12
A new stabilized FEM formulation for advective-diffusive-reactive problems is presented. The new method, called Spotted Petrov-Galerkin (SPG), combines two perturbations of quadratic Galerkin weight f...
