Sharing solutions for diverse problems

IMPRES, standing for Integrated Multiscale Porous media RESearch was established in 2014 by Dr. Vahid J. Niasar. The Integrated Multiscale Porous media RESearch (IMPRES) Group, established and led by Dr Vahid J Niasar in 2014, comprises 5 PhD students and 1 PDRA. IMPRES Group develops computational and experimental techniques to investigate multiphase flow, reactive transport, solid-fluid and fluid-fluid interfaces, and non-classical theories of porous materials to address fundamental problems in engineering and natural applications such as reservoir engineering, hydrogeology, environmental engineering, agricultural engineering, fuel cells, and membrane. Our mission is to enhance the in-depth understanding of fundamental porous media processes as well as to improve the numerical upscaling methods for multi-scale coupled problems.

Our current research portfolio covers:    

  • Fundamentals of multi-phase flow in porous materials,
  • Crop-soil interaction and nutrient cycles,
  • Micro-model experiments and image analysis,
  • Digital rock simulations and experiments,
  • Pore-to-continuum scale multiphysics modelling,
  • Multiscale and hybrid modelling.
  • As well as applications:

  • Contaminant transport and soil remediation,
  • Food security and agricultre,
  • Fuel cells and membranes,
  • Geological CO2 sequestration modelling,
  • EOR (LowSal, ASP),
  • Unconventional oil and gas reservoirs.
