Rotating effects on the photoionization cross-section of a 2D quantum ring

引用

Communications in theoretical Physics 2024年第10期76卷 153-159页

作者： Carlos Magno o Pereira Frankbelson dos S Azevedo Luís Fernando C Pereira Edilberto o Silva Departamento de Física Universidade Federal do Maranh?o

In this article, we investigate the nonrelativistic quantum motion of a charged particle within a rotating frame, taking into account the Aharonov–Bohm(AB) effect and a uniform magnetic field. our analysis entails the derivation of the equation of motion and the corresponding radial equation to describe the system. Solving the resulting radial equation enables us to determine the eigenvalues and eigenfunctions, providing a clear expression for the energy levels. Furthermore,our numerical analysis highlights the substantial influence of rotation on both energy levels and optical properties. Specifically, we evaluate the photoionization cross-section with and without the effects of rotation. to elucidate the impact of rotation on the photoionization process of the system, we present graphics that offer an appealing visualization of the intrinsic nature of the physics involved.

Characterization of Depleted Hydrocarbon Reservoir AA-01 of KoKA Field in the Niger Delta Basin for Sustainable Sub-Sea Carbon Dioxide Storage

引用

哈尔滨工程大学学报（英文版） 2024年第3期23卷 544-564页

作者： Patrick A.Eigbe olatunbosun o.Ajayi olabode t.olakoyejo Adekunle o.Adelaja Department of Mechanical Engineering University of LagosAkokaLagos State100213Nigeria Department of Aerospace Engineering Lagos State UniversityEpe CampusLagos State106101Nigeria

this study characterized the AA-01 depleted hydrocarbon reservoir in the KoKA field, Niger Delta, using a multidimensional approach. this investigation involved data validation analysis, evaluation of site suitability for Co_(2) storage, and compositional simulation of hydrocarbon components. the primary objective was to determine the initial components and behavior of the hydrocarbon system required to optimize the injection of Co_(2) and accompanying impurities, establishing a robust basis for subsequent sequestration efforts in the six wells in the depleted KoKA AA-01 reservoir. the process, simulated using industry software such as ECLIPSE, PVti, SCAL, and Petrel, included a compositional fluid analysis to confirm the pressure volume temperature(PVt) hydrocarbon phases and components. this involved performing a material balance on the quality of the measured data and matching the initial reservoir pressure with the supplied data source. the compositional PVt analysis adopted the Peng–Robinson equation of state to model fluid flow in porous media and estimate the necessary number of phases and components to describe the system accurately. Results from this investigation indicate that the KoKA AA-01 reservoir is suitable for Co_(2)sequestration. this conclusion is based on the reservoir's good quality, evidenced by an average porosity of 0.21 and permeability of 1 111.0 mD, a measured lithological depth of 9 300 ft, and characteristic reservoir – seal properties correlated from well logs. the study confirmed that volumetric behavior predictions are directly linked to compositional behavior predictions, which are essential during reservoir initialization and data quality checks. Additionally, it highlighted that a safe design for Co_(2) storage relies on accurately representing multiphase behaviour across wide-ranging pressure–temperature–composition conditions.
