Abstract: Underground hydrogen storage (UHS) and carbon dioxide capture and storage (CCS) have been the frontiers of energy transition of petroleum and coal industries. The similarities and differences of UHS and CCS are the key ...

Abstract: Due to high demand for the safe operation of structures, structural members with the potential to shift their natural frequencies/specific-stiffness to satisfy design requirements or avoid the occurrence of dynamical ...

Abstract: In this paper the so-called slightly reduced Navier-Stokes (SRNS) equations with most streamwise viscous diffusion and heat conduction terms are investigated in detail. It is proved that the ...

Abstract: Cooling of supercritical CH4 /N2 mixture is the most important heat transfer process during coalbed methane (CBM) liquefaction. In this paper, numerical studies of the turbulent convective heat ...

Abstract: Based on the existing unified hardening model, the double-state parameters unified hardening (DPUH) model is proposed, which can take into account the initial density and confining pressure dependent characteristics and ...

Abstract: Wind turbines are among the fastest-growing technologies for producing sustainable energy. Although numerous studies have been carried out to investigate the dynamic behavior of wind turbines exposed to synoptic winds, the ...

Abstract: Reverse osmosis (RO) desalination is the dominant desalination technology worldwide. The exergetic efficiency—which is recognized as a true measure from a thermodynamic viewpoint—of RO systems has been addressed by many ...

Abstract: The effectiveness of hydraulic fracturing is determined by the location of fracture initiation and the propagation. Previous research paid more attention to the control effect of geostress and construction-related parameters ...
