the aim of this research is to simulate oil spill behavior in the persian gulf due to the wind andtidal currents. this is achieved by coding an oil spill mathematical model consisting of several major submodels including hydrodynamic model, oil slick dynamic model and oil weathering model. the base of all of them is eulerian approach and they are coupled together to simulate spill incident in t...

background and aims: adenovector gene transfer induces inflammatory response that finally leads to vector removal from delivered site. the effect of hydrodynamic pre-injection on adenovector mediated liver inflammation remained elusive. materials and methods: different mice groups were pre-treated by hydrodynamic saline, dexamethasone or nothing prior to adeno-luciferase administration. their s...

an attempt is made for the first time to solve the quadratic and cubic model of magneto hydrodynamic poiseuille flow of phan-thein-tanner (ptt). series solution of magneto hydrodynamic (mhd) flow is developed by using homotopy perturbation method (hpm). results are presented graphically and the effects of non-dimensional parameters on the flow field are analyzed. the results obtained reveals ma...

Hydrodynamic behavior of aggregative fluidized beds has been studied and a model proposed for the prediction of different characteristics of fluidized beds. According to this model, a computer program is prepared and the hydrodynamic behavior of some industrial units has been simulated.

in the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. in this study, hydrodynamic coefficients of an autonomous un...

in this paper, a batch hydrogenation reactor performance was modeled using a hydrodynamic and reaction sub-models. the reaction expressions were obtained from the information reported in literature. experimental studies were conducted in order to generate the experimental data needed to validate the model. the comparison between the experimental data and model predictions seems quite satisfacto...

mathematical simulation of flow toward drains is an important and indispensable stage in drainage design and management. many related models have been developed, but most of them simulate the saturated flow toward drains without a due consideration of the unsaturated zone. in this study, the two dimensional differential equation governing saturated and unsaturated flow in porous media is numeri...
