  • Publication number: 20250045488
    Abstract: The present invention belongs to the field of computational mechanics, and provides an adaptive multi-level phase-field method for brittle fracture of elastic materials under thermal shock, thus to provide a new numerical calculation method for efficient fracture study. In the present invention, damage degree of a material is characterized by a phase field, and the multi-level hp-FEM is used as an adaptive strategy to implement dynamic discretization in a process of crack propagation under thermal shock. Compared with previous adaptive phase-field fracture models, the present invention has no hanging nodes, and has simple numerical implementation and high calculation efficiency, which can effectively predict the fracture behavior of a structure. At the same time, three pre-existing crack treatment techniques are developed to initialize the phase field.

  • Patent number: 12215921
    Abstract: A photoelectric hydrogen production energy storage and cold energy recovery coupled dry ice production device and a use method are disclosed. The device comprises a photoelectric conversion liquid hydrogen energy storage unit, photoelectricity participates in electrolysis of water in the storage unit to prepare hydrogen, and surplus hydrogen meeting downstream process requirements is liquefied in the unit; liquid hydrogen is output, so that intermittent photoelectric energy is converted into hydrogen energy to be stored. When hydrogen production through electrolysis of water is insufficient but industrial hydrogen is continuously used, high-grade and low-grade cold energy of low-temperature liquid hydrogen serving as cold sources in the unit is recovered from industrial tail gas purified CO2 and air separation nitrogen, liquid nitrogen and liquid CO2 are output and used for the storage unit and dry ice production respectively, and the liquid hydrogen is reheated and supplied to a downstream process.

  • Patent number: 6366728
    Abstract: An exemplary composite optical fiber transmission line and method are provided that result in significant advantages. The composite optical fiber transmission line includes a standard single-mode fiber, such as an SMF-28 fiber, a dispersion shifted fiber, such as an NZDSF fiber, and a dispersion compensating fiber. The single-mode fiber receives an input optical signal at a first end and generates a single-mode optical signal at a second end. The dispersion shifted fiber receives the single-mode optical signal at a first end and generates an output optical signal at a second end. The dispersion compensating fiber receives the output optical signal and generates a chromatic dispersion compensated optical signal that, preferably, is at some desired chromatic dispersion level. In one example, the residual chromatic dispersion of the composite optical fiber transmission line is zero or near zero, and the residual chromatic dispersion slope of the composite optical fiber transmission line is zero or near zero.
