Although fluid dynamics, a classical discipline, has been studied for many centuries, there are still many remaining questions yet to be answered, especially in turbulent flow. With significant advances in computational technology and decrease hardware costs, we have noticed a rapid evolution in CFD techniques and models
Discriminating multiphase methane (adsorbed and free phases) in coals is crucial for evaluating the optimal gas recovery strategies of coalbed methane (CBM) reservoirs. However, the existing volumetric-based adsorption isotherm method only provides the final methane adsorption result, limiting real-time dynamic characterization of multiphase methane in the methane adsorption process

For rock engineering projects, the cutting and fragmenting of rocks has attracted much attention. Exploring the fracture characteristics of rocks is helpful in achieving efficient and sustainable excavation for mining and tunneling engineering. The fracture toughness of rocks is a crucial mechanical indicator that weighs the initiation and extension of cracks during the breaking process.…
Alternating current field measurement (ACFM) technology has been used for sizing underwater structure cracks. However, conventional ACFM is more sensitive to cracks perpendicular to the induced current than cracks with other angles. In this paper, a rotating alternating current field measurement (RACFM) method and underwater test system are present for the detection of arbitrary-angle cr…
