Abstract:

The gas–solid coupling reaction kinetics at a constant temperature at each temperature point in the high-temperature cohesive zone in a blast furnace environment were simulated using industrial blast furnace raw material sinter, the low-reactivity conventional coke, and the high-reactivity unconventional coke. In this method, the coupling test of the sinter and coke at constant temperature was performed after a supporting thermogravimetric device was used to carry out pre-reduction, and the coupling reaction of industrial-grade sinter and coke were used to obtain the kinetic data and a mathema

Abstract:

The layout of directional high-level long boreholes in fracture zones for extracting pressure-relieved gas from goaf is a key technology to address the gas concentration exceedance in upper corners. To solve the gas exceedance issue at Fengtai Mine’s upper corner, this study established a gas–solid coupling model using COMSOL Multiphysics 6.3 based on actual mine parameters.

Abstract:

The finite volume method (FVM) was used to model a tungsten inert gas (TIG) arc welding process. A two-dimensional axisymmetric model of arc plasma integrating fluid–solid coupling was developed by solving electromagnetic and thermal equations in both the gas domain and the solid cathode. In addition, two additional coupling equations were considered in the gaseous domain where the arc is generated. This model also included the actual geometry of torch components such as the gas diffuser, the nozzle, and the electrode. The model was assessed using numerous numerical examples related to the pre

Abstract:

There are heat-fluid-solid multi-field coupling in the thermal recovery reservoir. At present, the researches on oil reservoir porous media coupling are mostly on fluid-solid. According to the oil reservoir characteristics, this paper puts forward the “white box” analysis model on the heat and mass transfer processes in thermal recovery reservoir. On this basis, the analysis and stimulation of the various porosity effects on heat and mass transfer processes use CMG software. This result can provide theoretical basis for enhancing oil/gas recovery.

Abstract:

Abstract Heat transfer in gas-solid two-phase flow is investigated numerically and experimentally. The numerical computations are carried out using four-way coupling Eulerian-Lagrangian approach. The effects of particle rotation and lift forces are included in the model. The gas-phase turbulence is modeled via low Reynolds number k-ε turbulence models. The SIMPLE algorithm is extended to take the effect of compressibility into account. The experimental study is performed using crushed limestone to simulate the solid phase. The effects of Reynolds numbers, particles size and temperature on the

Abstract:

The degradation of solid waste in landfills results in the coupled migration of gas and leachate through the pore spaces in waste material. The existing analytical methods cannot be used to obtain a solution for the gas–leachate coupled migration problem. This study used the differential quadrature method to solve the gas and leachate phase continuity equations considering the effect of the gas–leachate coupling. The calculation results were verified based on the calculated data of previous studies. The results of the field gas collection tests and the laboratory degradation tests were fitted

Abstract:

Axial flow compressor is an important component, so the compressor performance is of crucial. Fouling changes blade geometry and blade surface roughness is increased, thus aerodynamic performance is affected. The flow of gas phase and gas-solid coupling phase are implemented to reveal the effect of inlet condition on particle deposition. Based on Euler-Lagrange model, this paper made numerical simulation of gas-solid two phase flow in the axial flow compressor rotor cascade. Simulation result shows that the increase of inlet temperature can result in the reduction of particle volume fraction.

Abstract:

Gas-solid interfacial reaction is critical to many technological applications from heterogeneous catalysis to stress corrosion cracking. A prominent question that remains unclear is how gas and solid interact beyond chemisorption to form a stable interphase for bridging subsequent gas-solid reactions. Here, we report real-time atomic-scale observations of Ni-Al alloy oxidation reaction from initial surface adsorption to interfacial reaction into the bulk. We found distinct atomistic mechanisms for oxide growth in O2 and H2O vapor, featuring a “step-edge” mechanism with severe interfacial strai
