MODELING GASEOUS CAVITY IN FLUID FLOW

Fluid Flow Modeling in Fractures

In this paper we study fluid flow in fractures using numerical simulation and address the challenging issue of hydraulic property characterization in fractures. The methodology is based on Computational Fluid Dynamics, using a finite-volume based discretization scheme. Steady-state, viscous, laminar flow simulations for a Newtonian fluid are carried out in both 2D and 3D fracture models. In 2D,...

An Alternating Direction Implicit Method for Modeling of Fluid Flow

This research includes of the numerical modeling of fluids in two-dimensional cavity. The cavity flow is an important theoretical problem. In this research, modeling was carried out based on an alternating direction implicit via Vorticity-Stream function formulation. It evaluates different Reynolds numbers and grid sizes. Therefore, for the flow field analysis and prove of the ability of the sc...

Investigation of Cavity Flow Aerodynamics Using Computational Fluid Dynamics

The acoustic environment of a bomb bay or cavity causes large pressure oscillations and the severity of them is a problem that has intrigued researchers for years [68]. Many suppression techniques have been applied with varying degrees of success. Despite this, the understanding of why the pressure oscillations exist or how the suppression methods work have not been investigated as thoroughly. ...

Transient Fluid Flow Modeling in Fractured Aquifer of Sechahoon Iron Mine Using Finite Element Method

Considering the fact that a large volume of iron reserve in the Sechahoon Iron Mine in Yazd Province has located under the water table, it is necessary to conduct a comprehensive study on water flow within the pit and its surroundings. The conceptual model of the aquifer was created using surface and underground geological information compared with water table data of the area of interest. In t...
