Накратко на български
Потоците от газ в изключително тесни пори, като тези в шистовите скали, се анализират чрез нови математически методи и суперкомпютри. Това помага за по-доброто разбиране на добива на метан и съхранението на въглероден диоксид в земната кора.

Efficient pore-scale kinetic simulation of gas flows in ultra-tight porous media
Gas flows in tight porous media with low-permeability are of great interest in numerous industrial applications, e.g., extraction of methane gas from ultra-tight rocks like shale, and geological storage of CO2 to tackle the global warming. Therefore, it is important to understand and quantify the gas flows in these low-permeability porous media with pore spaces as small as a few nanometers across. In this project, novel mathematical methods are developed to directly study the gas flow in these unconventional porous media at the micro scale, for which the established classical models fail. These methods are based on the gas kinetic theory which deals with the distribution of gas molecules’ velocity, directly in the pore space of porous materials. We also develop advanced computer programs implementing the methods that can effectively run on massively parallel computer systems such as the UK’s academic supercomputer, AECHER. Using these tools, the classical models can be examined in details for their validity and new models can be developed based on the pore-scale studies.

Цел на проекта
The conventional Darcy-type of models based on continuum fluid theory fail to capture the non-equilibrium flow physics of gas transport in ultra-tight porous media such as shale rocks. Instead of using these conventional models, this project aims to develop a new gas kinetic solver which is computationally efficient to allow direct pore-scale simulations of gas flows using 3D scanned digital images of rock samples, which can uncover often non-intuitive flow phenomena in ultra-tight porous media. This work has far reaching impact from quantifying extraction of natural gas from unconventional gas reservoirs to optimising design of porous material based thermal protection systems of entry vehicles.The gas kinetic solver will be based on the Boltzmann-BGK equation which can accurately describe low-speed gas flows in the entire range of Knudsen number, thus provides a unified approach for simulating gas flows in ultra-tight porous media where the pore sizes are widely distributed from a few nanometres to several hundred microns. Specifically, the Fellow will (a) develop an efficient numerical scheme and a massively multi-level parallel kinetic solver; (b) perform pore-scale simulations, experimental validations and systematic examination of the current phenomenological Darcy-type of models based on the realistic porous media samples.The new simulation capability will help us to shape the emerging research area of gas transport in ultra-tight porous media. The Fellow is currently at forefront of international advances in modelling and simulation of the gas flows at micro/nano scales. With support from three hosting institutions i.e. University of Strathclyde, Aix-Marseille University and Heriot-Watt University, a timely award of the Marie Skłodowska-Curie Fellowship will provide the applicant the necessary resources and access to expertise to make rapid progress in this emerging research area and become an independent researcher, ready to compete globally.
