Abstract We present a comprehensive dataset of two-phase flow Lattice-Boltzmann simulations, generated using over 100 million GPU hours, covering a wide range of wetting conditions, capillary numbers, and porous geometries. While multiphase flow has traditionally been studied through laboratory experiments, the growing power of computational simulations provides a scalable and efficient alternative.

1 Introduction For decades, various underground applications such as oil and gas production, contaminant transport, and CO2 sequestration have been proposed for resource recovery and energy storage, with flow and solute transport playing an important role in these processes (Holditch, 2013; Maitland, 2000; Xiaoguang et al., 2018).

Abstract Proton exchange membrane fuel cells, consuming hydrogen and oxygen to generate clean electricity and water, suffer acute liquid water challenges. Accurate liquid water modelling is inherently challenging due to the multi-phase, multi-component, reactive dynamics within multi-scale, multi-layered porous media. In addition, currently inadequate imaging and modelling capabilities are limiting simulations to small areas (<1 mm2) or simplified architectures.
