CFD–DPM Simulation Study of the Effect of Powder Layer Thickness on the SLM Spatter Behavior
Autor: Liu Cao, Qindan Zhang, Ruifan Meng
Publikováno v: Metals, Vol 12, Iss 11, p 1897 (2022)
Selective Laser Melting (SLM) has significant advantages in manufacturing complex structural components and refining the alloy microstructure; however, spatter, as a phenomenon that accompanies the entire SLM forming process, is prone to problems suc

Constitutive modeling for the flow stress behaviors of alloys based on variable order fractional derivatives
Autor: Ruifan Meng, Liu Cao, Qindan Zhang
Publikováno v: Materials Research Express, Vol 9, Iss 9, p 096508 (2022)
During hot working, alloys may experience three kinds of flow stress behaviors, including strain hardening, strain softening, or steady flow, because of the competition of work hardening and thermal softening. Modelling the flow stress behaviors play

Coalescence of a Ferrofluid Drop at Its Bulk Surface with or without a Magnetic Field
Autor: Qindan Zhang, Souhila Poncin, Christian Blanchard, Youguang Ma, Huai Z. Li
Publikováno v: Langmuir. 39:461-468
The coalescence of a ferrofluid drop at its bulk surface, with or without a magnetic field, was investigated experimentally by a high-speed camera. Shape deformations of both the pendant ferrofluid drop and the bulk surface in the axial direction wer

Self-Sustained Coalescence–Breakup Cycles of Ferrodrops under a Magnetic Field
Autor: Youguang Ma, Huai Z. Li, Qindan Zhang, Yining Wu
Publikováno v: Langmuir
Langmuir, American Chemical Society, 2019, 35 (37), pp.12028-12034. ⟨10.1021/acs.langmuir.9b02046⟩
The self-sustained coalescence-breakup cycles of ferrodrops were investigated for the first time by a high-speed camera under various magnetic fields. Under an axial magnetic field, the upper ferrodrop would deform into a conic shape before coalescin

Manipulation of microdroplets at a T-junction: Coalescence and scaling law
Autor: Youguang Ma, Chunying Zhu, Kai Wang, Qindan Zhang, Taotao Fu, Guangsheng Luo, Rui Ma
Publikováno v: Journal of Industrial and Engineering Chemistry. 65:272-279
The manipulation of a droplet at a microfluidic T-junction is achieved via adding reagents into the droplet with the same solution. Three types for droplet coalescence at the T-junction were observed: tail coalescence, slipping coalescence and unstea

Initial coalescence of a drop at a planar liquid surface
Autor: Taotao Fu, Qindan Zhang, Xiaofeng Jiang, Huai Z. Li, David Brunello, Youguang Ma, Chunying Zhu
Publikováno v: Physical Review E
Physical Review E, American Physical Society (APS), 2019, 100 (3), ⟨10.1103/PhysRevE.100.033112⟩
The initial coalescence of a pendant drop at bulk liquid was jointly investigated by an ultrahigh-speed DC electrical device, a high-speed camera, and a fast micro-Particle Image Velocimetry (micro-PIV). Extended to highly viscous non-Newtonian liqui

Formation of droplet and 'string of sausages' for water-ionic liquid ([BMIM][PF6]) two-phase flow in a flow-focusing device
Autor: Cai Liu, Huai Z. Li, Youguang Ma, Taotao Fu, Qindan Zhang, Chunying Zhu
Publikováno v: Chemical Engineering and Processing: Process Intensification
Chemical Engineering and Processing: Process Intensification, Elsevier, 2018, 125, pp.8-17. ⟨10.1016/j.cep.2017.12.017⟩
Dynamics of water-high-viscosity ionic liquid ([BMIM][PF6]) two-phase flow in a flow-focusing device were investigated by using a high-speed digital camera. Four flow regimes were identified: dripping, jetting, irregular and string of sausages. The r
