Taylor drop in a closed vertical pipe

Experimental Investigations on the Thermal Performance of a Vertical Closed Loop Pulsating Heat Pipe Using Binary Mixture of Fluids

This paper presents the experimental investigations conducted on a vertical closed loop pulsating heat pipe (VCLPHP) to evaluate the thermal performance. The values of thermal resistance and heat transfer coefficient obtained in the experimentation is used as evaluation parameters. The VCLPHP used has capillary tubes having an inner diameter of 2mm and outside diameter 3mm and bent into 5 turns...

Taylor bubble rising in a vertical pipe against laminar or turbulent downward flow: symmetric to asymmetric shape transition

Viscoelastic effects on drop deformation in a converging pipe flow

his paper reports finite-element simulations of drop deformation in converging flows in an xisymmetric conical geometry. The moving interface is captured using a diffuse-interface model nd accurate interfacial resolution is ensured by adaptive refinement of the grid. We have explored he effects of viscoelasticity on drop deformation when either the drop or the matrix is a Giesekus uid. Contrary...

Pressure Drop of Pipe Flow in a Manifold Block

We deal with a solid manifold block and a laminated manifold block that are used for connecting hydraulic components. They are useful for reducing the space and weight of hydraulic systems. We investigate pressure drops of their pipe flow with computational fluid dynamics (CFD) and compare those of two types. The majority of all pressure drops in both types is pressure drop at corners. In solid...

Experimental Analysis of a Vertical Drop Shaft

An experimental campaign is undertaken in order to investigate the hydraulic features of a vertical drop shaft, also considering the influence of a venting system consisting of a coaxial vertical pipe, projecting within the drop shaft with different plunging rates. Three different flow regimes are observed: a “weir flow” for very low head values, where the flow profile is subject to the atmosph...
