چکیده

Effective finite transport speeds are crucial to many situations of great industrial and medical importance. Traditional finite speed transport models are critically reviewed and new models are introduced. It is concluded that realistic finite speed models with constant coefficients cannot be local in space and are either local in phase-space or non local in space; models with time-dependent coefficients are also considered.

روش مسیر یابی ذره به منظور پیش بینی حرکت نفت در دریا

A two-dimensional two-phase numerical model is developed to predict transport and fate of oil slicks which resulted the concentration distribution of oil on the water surface. Two dimensional governing equation of fluid flow which consists mass and momentum conservation was solved using the finite difference method on the structured staggered grid system. The resulted algebric equations were so...

Subsurface Transport Modeling Using Adaptive Finite Elements

A multi-dimensional finite element method (GWADAPT) which utilizes local mesh adaptation is used to calculate groundwater flow and subsurface transport of contaminant in saturated and unsaturated conditions. The model uses simple modifications to increase computational speed and reduce storage, allowing the model to run on PCs and workstations. GWADAPT can be accessed from the web and downloade...

Effect of Pullback Speed and the Distance between the Skin and Vein on the Performance of Endovenous Laser Treatment by Numerical Simulation

Introduction: Endovenous laser treatment (ELT) is a new treatment method for the reflux of the great saphenous vein. A successful ELT is dependent on the selection of optimum parameters required to achieve optimal vein damage while avoiding side effects including skin burns. The mathematical modeling of ELT can be used to understand the process of ELT. This study was conducted to examine the ef...
