RISExergy Destruction Mechanism of Coal Gasification by Combining the Kinetic Method and the Energy Utilization Diagram
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gasification is the core unit of coal-based production systems and is also the site where one of the largest exergy destruction occurs. This paper reveals the exergy destruction mechanism of carbon gasification through a ...
Hamiltonian-Based Derivation of the High-Performance Scaled-Boundary Finite-Element Method Applied to the Complex Multilayered Soil Field in Time Domain
Publisher: American Society of Civil Engineers
Abstract: Wave propagation in a two-dimensional unbounded domain with rigid bedrock was studied. The study was based on the scaled-boundary finite-element method (SBFEM) combing the continued fraction method. The SBFEM is a novel ...
Coal Based Cogeneration System for Synthetic/Substitute Natural Gas and Power With CO2 Capture After Methanation: Coupling Between Chemical and Power Production
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cogeneration of synthetic natural gas (SNG) and power from coal efficiently and CO2 capture with low energy penalty during coal utilization are very important technical paths to implement clean coal technologies in China. ...
Dynamic Impedance Functions for Arbitrary-Shaped Rigid Foundation Embedded in Anisotropic Multilayered Soil
Publisher: American Society of Civil Engineers
Abstract: This paper presents a hybrid numerical method for the evaluation of dynamic impedance of rigid foundation embedded in anisotropic multilayered soil. The proposed approach includes two main parts: (a) the solution of wave ...
Novel Coal-Steam Gasification With a Thermochemical Regenerative Process for Power Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a novel high-efficiency coal gasification technology is proposed in which a regenerative unit is applied to recover syngas sensible heat to generate steam; then, the high-temperature steam is used to gasify ...
Plate-Bending Analysis by NURBS-Based Scaled Boundary Finite-Element Method
Publisher: ASCE
Abstract: This paper extends the idea of using nonuniform rational B-splines (NURBS) based shape functions in the scaled boundary finite-element method (SBFEM) to plate bending formulations, which inherits the advantages of the ...
