    Parameter Analysis of CO2 Capture with Anti-Sublimation Process

    Hua Tian1, Ke Kang1, Lingfeng Shi2,*, Rui Sun1

    Energy Engineering, Vol.117, No.5, pp. 267-277, 2020, DOI:10.32604/EE.2020.011440

    Abstract The anti-sublimation CO2 capture technology has attracted the attention of researchers due to its advantages such as no pollution and high product purity. The anti-sublimation process is the core link of this technology, so the study of this process is of great significance to the low-temperature capture system. At present, there are few research works on the CO2 anti-sublimation process. In order to study the influence of key parameters on the capture performance during CO2 anti-sublimation, a one-dimensional steady-state of CO2 anti-sublimation process in a double pipe heat exchanger was established based on the mixture gas of N2 and CO2.… More >

    Application of Meshfree Method to Elastic-Plastic Fracture Mechanics Parameter Analysis

    S. Hagihara1, M. Tsunori2, T. Ikeda3, N. Miyazaki3

    CMES-Computer Modeling in Engineering & Sciences, Vol.17, No.2, pp. 63-72, 2007, DOI:10.3970/cmes.2007.017.063

    Abstract The element-free Galerkin (EFG) method is applied to the calculation of elastic-plastic fracture mechanics parameters such as the J-integral and T*-integral. The fields of displacement, strain and stress for a crack problem are obtained using the elastic-plastic EFG method. Then the elastic-plastic fracture mechanics parameters J-integral and T*-integral are calculated from path and domain integrals. In the finite element analysis, paths for the path integral and domains for the domain integral are selected depending on finite element mesh division. On the other hand, they can be arbitrarily selected in the EFG method, and we can use a simple integral path… More >
