      • Study on Dust Particle Deposition Movement in Pipe of FF System

        Fan bailin,Huang ganghan,Wang Hongwei,Shan Quanfeng 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.2

        The Particle deposition position and subside curve equation was studied. Particle depositing Para-curve formula was generated through the dust particle dynamic analysis in the pipe. Settlement nephogram and the trajectory curve of dust particle were obtained by FLUENT numerical simulation. Depositing velocity of particle was simulated and the simulation results, the calculated results and the experimental result were compared and analyzed. The particle motion was reflected by coordinate equation and parabolic curves were drawn for the particle No.65 in the z direction. Various depositing velocities in horizontal rectangle pipe under different particle diameter and flow velocity circumstances were compared to summarize motion patterns.

        Discussion of the Influence of Geometric Discontinuity and Stress Concentration on the Magnetic Memory Method

        Gang Han,Haihong Huang 한국자기학회 2020 Journal of Magnetics Vol.25 No.2

        In this study, a multi-physics finite element model is adopted to investigate the effect of geometric discontinuity and stress concentration on the magnetic memory method (MMM). We propose a quadratic equation to fit the stress magnetization constitutive relation in the model. The relation can be used to predict the abnormality of the geometric discontinuity and the stress concentration. Simulation results show that the magnetization on the wall of the groove is the weakest and that on the bottom of the groove is the maximum. The free boundary condition releases the stress concentration of the defect. Although the magnetization induced by stress concentration is weaker than geometric discontinuity, the signal characteristics can still be used to evaluate the defect and the stress. This work proves that the MMM is a potential method for stress distribution assessment.
