on the turbulence jet model, with respect to Ar-He mixture plasma gas injecting to ambient atmosphere, the temperature filed and velocity field under typical working conditions were investigated...; plasma jet; temperature field; velocity field _______________________________________________________________ 1 Introduction In plasma spray, the distributions of temperature and velocity......
numerical simulation is always appealed to get the velocity field. Clearly, a detailed analysis of the flow in the EM stirred region of the molten pool is important to evaluate its effect on various...Article ID: 1003-6326(2005)02-0447-05 Modeling of velocity field for vacuum induction melting process CHEN Bo(陈 波), JIANG Zhi-guo(江治国), LIU Kui(刘 奎), LI Yi-yi(李依依) (Institute of Metal......

and the secondary atomizer, on gas flow field were investigated by simulation. The effects of primary pressure on gas velocity at the centerline were compared. Water atomizing experiment was carried out to validate...; 1 MPa on gas flow with a constant secondary pressure of 1 MPa. The gas flow field is illustrated in Fig.5(a) when only the secondary atomizer is applied. The velocity streamline distribution......
investigated. Key words: phase field method; forced flow; strong anisotropy; faceted dendrite; steady state tip velocity 1 Introduction Dendrites are common shapes in the melt solidification... anisotropy value in a forced flow was presented, and the effects of anisotropy parameters, flow velocity, undercooling and compound flow on the faceted dendrite shape were investigated. 2 Phase field......
the opening degree is increased to 0.8 mm, although the flow velocity distribution of the fluid in the flow field tends to be relatively stable, there is still a large vortex. Figure 9 Curve... was carried out. The pressure distribution and flow velocity distribution of the internal flow field model under two-hole and three-hole spool structures were analyzed. The results show that the vortex......

in the field, errors from the velocity measurement can be avoided in comparison to three traditional velocity models. By analyzing 24 different cases, the proposed multidirectional velocity model iterated...An improved multidirectional velocity model for micro-seismic monitoring in rock engineeringLI Jian(李健)1, 2, WU Shun-chuan(吴顺川)1, GAO Yong-tao(高永涛)1, LI Li-jie(李莉洁)3, ZHOU Yu(周喻)1(1.
