PoreXpert Ltd was set up to disseminate £4.5m of research into porous materials carried out at the University of Plymouth, UK. Its core activities are sales of the software, which is under constant development, and consultancy based on use of the software and expertise on the experimental measurements to generate data for the model. The software is world-leading, patented and trademarked. Nearly any type of porous material can be studied - catalysts (except zeolites), nuclear carbon, paper coatings, filters, sinters, soil, sandstone and tight-oil shale to name but a few. Simulations of pore-fluid properties include permeability, percolation, tortuosity and diffusion, filtration and thermal conductivity. Highly deformable materials (such as fibrous mats), highly porous (>95%) materials or macro-cracked materials such as cracked carbonate rock are not modellable.
