The explosive viscous liquid becomes inject to warhead by discharge system. The injection device is consisted of a piston to move down and leads the viscous fluid through the cylindrical pipe towards the end of the duct. Then the viscous fluid leads into a convergent path that will be injected to the warhead or other injection equipment. In this project, the path of viscous fluid flow is divide...

the paper numerically presents laminar forced convection of a nanofluid flowing in a duct at microscale. results were compared with both analytical and experimental data and observed good concordance with previous studies available in the literature. influences of brinkman and reynolds number on thermal and hydrodynamic indexes have been investigated. for a given nanofluid, no change in efficie...

Bio-oil produced from conventional flash pyrolysis has poor quality and requires expensive upgrading before it can be used as a transportation fuel. In this work, a high quality bio-oil has been produced using a novel approach where flash pyrolysis, catalysis and fractionation of pyrolysis vapors using two stage condensation are combined in a single process unit. A bench scale unit of 1 kg/h fe...

Water flooding technology is an important measure to enhance oil recovery in oilfields. Understanding the pore-scale flow mechanism water process of great significance for optimization development schemes. Viscous action and capillarity are crucial factors determination rate flooding. In this paper, a direct numerical simulation (DNS) method based on Navier–Stokes equation volume fluid (VOF) em...

Abstract A numerical model is investigated representing counter-current spontaneous imbibition of water to displace oil or gas from a core plug. The based on mass and momentum conservation equations in the framework theory mixtures. We extend previous that included fluid–rock friction fluid–fluid drag interaction (viscous coupling) by including fluid compressibility Brinkman viscous terms. Gas ...

Abstract A CFD study on horizontal oil-water flow with high viscosity ratio (O(103)) was conducted the VOF multiphase model in conjunction SST k–? turbulence scheme. Suitable settings of models and numerical solution were highlighted. Particularly, wall contact angle is shown to be important regarding oil fouling phenomenon commonly seen water-lubricated transportation highly viscous oil. Satis...

This paper aims to investigate the frictional and wear performances of natural flax fibers reinforced polypropylene composites subjected lubricated mechanical polishing. Particularly, interactions between biocomposite surfaces two different liquids (oil water) are considered using a rotary tribometer where counter-face is fed by silicon carbide (SiC) abrasive papers. Friction at dry, water oil-...
