EFFECT OF LINEAR DRIFT ON RADIAL TRANSPORT OF TRACER IN HOMOGENEOUS POROUS MEDIA
Abstract:
Transport phenomena in porous media play a crucial role in various natural and engineered systems, such as groundwater flow, oil recovery, and contaminant transport. Understanding the behavior of tracers in porous media is essential for predicting the movement and dispersion of solutes. In this study, we investigate the effect of linear drift on the radial transport of a tracer in homogeneous porous media.
The transport process of the tracer in porous media is influenced by several factors, including advection, diffusion, dispersion, and the presence of external forces. The linear drift, also known as a pressure gradient or velocity gradient, represents an external force that can significantly impact the transport behavior of the tracer. It occurs when there is a linear variation in pressure or velocity across the porous medium.
To analyze the effect of linear drift on radial transport, we develop a mathematical model based on the advection-diffusion equation. The model incorporates the linear drift term as an additional driving force. We consider a homogeneous porous medium, assuming isotropic and uniform properties throughout the domain.
Through numerical simulations, we investigate the impact of various parameters, such as the magnitude and direction of the linear drift, the initial concentration distribution, and the porosity of the medium. We analyze the tracer’s breakthrough curves, which provide insights into the transport behavior and the dispersion of the tracer plume. The results enable us to understand how the linear drift affects the transport process, including the breakthrough time, peak concentration, and spreading of the tracer.
Our findings reveal that the linear drift can significantly alter the transport characteristics of the tracer in radial flow scenarios. The magnitude and direction of the linear drift influence the transport behavior, with higher drift rates resulting in faster breakthrough and increased lateral spreading. Moreover, the initial concentration distribution and porosity of the medium also play important roles in determining the tracer’s transport behavior under linear drift conditions.
This study enhances our understanding of the transport processes in homogeneous porous media and provides valuable insights for applications such as groundwater management, contaminant remediation strategies, and enhanced oil recovery techniques. The findings can assist in optimizing the design and operation of such systems to improve their efficiency and minimize potential environmental risks.
