Fractal porous media are a special class of porous media characterized by their highly heterogeneous and self-similar structure. This complexity poses significant challenges for traditional modelling approaches, which often fail to capture the intricate flow and transport dynamics observed in these systems.

Fractal Porous Media: A Unique Challenge

The fractal nature of porous media gives rise to unique challenges in modelling flow and transport processes. The highly irregular pore geometry and connectivity result in:

• Heterogeneity: Fractal porous media exhibit significant variations in pore size, shape, and connectivity, leading to complex flow patterns.
• Tortuosity: The tortuous nature of flow paths increases the effective distance travelled by fluids and solutes, affecting their transport rates.
• Scale dependency: The flow and transport properties of fractal porous media vary with the scale of observation, requiring multi-scale modelling approaches.

These challenges necessitate the development of specialized modelling techniques that can accurately capture the complex behaviour of fractal porous media.

Modelling Flow and Transport in Fractal Porous Media

This comprehensive book provides a systematic overview of the state-of-the-art in modelling flow and transport in fractal porous media. It covers a wide range of topics, including:

• Darcy's law and its extensions: The fundamental governing equations for flow through porous media, modified to account for fractal heterogeneity.
• Navier-Stokes equations: Detailed analysis of the Navier-Stokes equations for modelling flow at the pore scale, capturing the effects of viscous forces and pore geometry.
• Pore-scale modelling: Advanced techniques for simulating flow and transport at the pore level, providing insights into the microscopic mechanisms governing flow behaviour.
• Numerical methods: Computational techniques for solving the governing equations, including finite element methods, finite volume methods, and lattice Boltzmann methods.
• Analytical solutions: Simplified analytical solutions for specific flow and transport scenarios, providing valuable insights into the underlying processes.

The book also explores the application of modelling techniques to real-world problems, such as groundwater flow and contamination, oil and gas recovery, and porous media heat transfer.
