Effects of horizontal vibration on hopper flows of granular materials
This study experimentally examines the flow of glass spheres in a wedgeshaped hopper that is vibrated horizontally. When the hopper is discharged without vibration, discharge occurs as a hnnel flow, with the material exiting the central region of the hopper and stagnant material along the sides. With vibration, the discharge of the material occurs in reverse, with the material along the sides e...
متن کاملHeat transfer enhancement due to air bubble injection into a horizontal double pipe heat exchanger
If an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. Air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. This mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. Howeve...
متن کاملPredicting the settlement of coarse granular materials under vertical loading
Granular materials are widely used in industrial processes despite their complex and poorly understood mechanical behaviour both in static and dynamic regimes. A prototypical example is the settlement and compaction of a granular bed under vibrational loading. The elementary mechanisms of this process are still unclear and there is presently no established theory or methodology to predict the s...
متن کاملStationary core-annular flow through a horizontal pipe.
A theoretical investigation has been made of core-annular flow: the flow of a high-viscosity liquid core surrounded by a low-viscosity annular liquid layer through a horizontal pipe. Special attention is paid to the question how the buoyancy force on the core, caused by a possible density difference between the core and the annular layer, is counterbalanced. From earlier studies it is known tha...
متن کاملAn Experimental Correlation for Friction Factor in Horizontal Pipe with Trapezoidal Section Inner Longitudinal Slots for Conveying of Solids
In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and Froude number is presented. It is shown that the mixture friction factor for pipes with inn...
