This paper presented experimental and numerical studies to investigate pressure drop in perforation horizontal wellbore with a 90° phasing 20 spm density. The apparatus has been constructed calculate the static exit velocity pipe after mixing axial flow radial through perforations wellbore. specifications of used were inner diameter is 44 mm, length 2 m, 4 mm. For this objective, simulation mod...

We analyze the pressure-driven flow of a viscoelastic fluid in arbitrarily shaped, narrow channels and present theoretical framework for calculating relationship between rate $q$ pressure drop $\Delta p$. utilize Oldroyd-B model first identify characteristic scales dimensionless parameters governing lubrication limit. Employing perturbation expansion powers Deborah number ($De$), we provide ana...

In the present study, a compact analytical model is developed to determine the pressure drop of fully-developed, incompressible, and constant properties slip-flow through arbitrary cross-section microchannels. An averaged firstorder Maxwell slip boundary condition is considered. Introducing a relative velocity, the difference between the bulk flow and the boundary velocities, the axial momentum...

Small-diameter ultrasonic flow meters present an interesting industrial internal-flow problem due to their unique geometry and complex interaction with fluid flow. In order efficiently evaluate optimise these meters, physics must be accurately understood predicted. this study, computational dynamics is used predict the turbulent inside a residential meter intrusive two-stand configuration. Reyn...

On many occasions, fan or compressor stages have to face azimuthal flow distortion at inlet, which affects their performance and stability. These distortions can be caused by external events some particular geometrical features. The aim of this work is propose a joined numerical experimental analysis the behavior in single axial stage under distortion. are generated different grids that placed ...

More and more biomolecules are being produced by the biotechnology industry for applications ranging from medicine and food to engineering materials. Liquid chromatography plays a center-stage role in a typical downstream process producing biomolecules such as recombinant proteins. Rigid gigaporous media are porous particles possessing large transecting through-pores with a pore-to-particle dia...

This study investigates the pressure-drop behaviour associated with airflow through bulk and structurally tailored multi-layered, open-cell porous Inconel structures over a wide airflow velocity range (0-50 m s). The effect of airflow velocity on the pressure-drop behaviour as a function of the sample thickness is presented and related to the flow behaviour corresponding to the relevant flow re...
