Experimental study of two-phase flow patterns through an inclined rectangular channel with horizontal and vertically upward directions

Publication Type: Academic Journal

Source(s): Alexandria Engineering Journal, Vol 62, Iss , Pp 445-453 (2023)

Abstract: In this paper, an experiment is carried out to recognize the flow pattern and to measure the void fraction of gas–liquid two-phase flow in an upward inclined channel (horizontally to vertically upward). The experiments are performed in a 30-m channel w...

River rhythmicity: A conceptual means of understanding and leveraging the relational values of rivers

Publication Type: Academic Journal

Source(s): People and Nature, Vol 4, Iss 4, Pp 949-962 (2022)

Abstract: Abstract River rhythmicity refers to the periodic, recurrent phenomena of a riverscape that are synchronized with the rise and fall of river water, creating regimes of river time. River rhythmicity can serve as a lens into the temporal dimension of riv...

An LES-Like Multiscale Multiphase Flow Model Based on Break-up and Coalescence Phenomena

Publication Type: Academic Journal

Source(s): Journal of Applied Fluid Mechanics, Vol 15, Iss 4, Pp 1073-1085 (2022)

Abstract: The multiscale multiphase flow contains both small-scale (dispersed phase) and large-scale (continuous phase) structures. Standard interface-averaging multiphase models are appropriate for the simulation of flows including small-scale structures. Stand...
