The purpose of this work is to experimentally find factors, which affect this phenomenon, and to develop a method to avoid such stoppage in pipelines. Experiment was done in two different pipelines. The one consists of aluminum tubes whose inside diameter is 30 mm and total length is 300 m....
Uluasarslan and Teke, 2008, Uluasarslan and Teke, 2009 have carried out extensive experimental instigations on the transport of capsules of ψ = 1 in HCPs for on-shore applications (i.e. horizontal pipelines), developing expressions for capsules’ velocity and pressure drop within the HCP. It...
EMPIRICAL PRESSURE AND VELOCITY CORRELATIONS FOR CYLINDRICAL CAPSULES CONVEYED IN PIPELINES UP TO 4 INCHES IN DIAMETER The pressure gradient to maintain a particular capsule velocity is increased substantially by an increase in capsule specific gravity, but is little affect...

Design parameters of pipelines for capsule flow (i.e., power of pumps, number of pumps, diameters of capsules, diameter of pipe, etc.) can be calculated if pressure drops of such pipelines are estimated. All major and minor losses that incur at various levels depending on the diameter and...
PIPELINESSTATIC frictionDRAG forcePIPE bendingCOMPUTER simulationAs the process before the transporting of the capsule in a hydraulic capsule pipeline system, the capsule's threshold of motion process is often tested in the horizontal straight pipe. However, the result of the physical test ...
Design parameters of a pipelines capsule flow can be calculated if dependence of pressure drops on flow velocity and capsule concentration of such pipelines are known. For this purpose, loss coefficients of elbows were studied experimentally in pipeline loop of I.D. 0.1 m. Elbows with central ...
of pipelines in which capsules flow can be developed if the pressure drops (螖P)m caused by the two-phase flow are known. Therefore designers are in need of a general pattern to calculate the pressure drops. Slurry flow mechanism is different from capsule flow mechanism, so that expressions ...

Velocity ratioAn experimental investigation was carried out to determine pressure drops of the flow of a two-phase mixture of spherical ice capsules and water inside the pipelines of cooling systems. Instead of ice capsules, spherical capsules made of polypropylene material whose density (870kg/m) ...
