... the solution of the impact parameters of solid particles. When calculating the droplet deposition rate of annular flow, the conversion coefficient proposed by EMMM is used to correct the variance of the particle displacement. The proportion of the particles deposited is calculated by solving the probability...

... technologies at the local scale. This paper uses X-ray computed tomography (CT) imaging to describe the local time-average gas holdup differences of annular hydrodynamic structures that arise through axisymmetric annular flow in a 10.2 cm and 15.2 cm diameter cold flow fluidized bed. The aeration scheme used...

.... Emphasis is put on the annular flow pattern of liquid vapor two-phase flow since this regime is the last encountered two-phase regime and has a higher heat transfer coefficient among other two-phase flow patterns. Attempts are made to employ the least possible simplification assumptions and empirical...

...Y. Liu; W. Z. Li The liquid droplet size distribution in gas-liquid vertical upward annular flow is investigated through a CFD (computational fluid dynamics)-PBM (population balance model) coupled model in this paper. Two-fluid Eulerian scheme is employed as the framework of this model...

... for termination of the iterative process were for both the norm-of-the-error and the norm-of-the-residuals < 10 − 4 , and for the maximum free surface change < 10 − 5 . Due to the two free surfaces present in annular flows, under-relaxation for the movement of the free...

... swelling annular flow extrudate swell exit correction pipe extrusion blow molding Newtonian fluid weak compressibility wall slip linear law Annular flow occurs in many processes, such as blow molding and pipe extrusion in polymer processing ( 1 ), or in any material flow between two...

... for Gas-Liquid Annular Flow in a Horizontal Pipe,” PhysicoChem. Hydrodynam., Vol. 6, pp. 179–195). The circumferential momentum equation is simplified to a balance between the normal Reynolds stress in the film’s circumferential direction and the circumferential component of the weight of the film...
