This study aims to derive basic principles for liquid mass flow scaling of gas-assisted coaxial nozzles. Four steps were investigated in the range M˙liq = 20–500 kg·h−1, applying four atomizers with similar geometry designed at Weaero= const. High-speed camera and phase Doppler anemometer utilized detect local droplet size distribution. To estimate a reliable measurement plane, detection method...

A compact static mixer for gas–liquid dispersion in pipelines is studied this paper with a Reynolds averaged two fluid model approach. procedure based on the lumped parameter solution of population balance applied to obtain bubble Sauter mean diameter needed interphase forces. The gas distribution pipe analyzed different operative conditions and efficiency assessed terms homogeneity section, lo...

In this work, steady-state droplet size distributions in a DN300 stirred batch vessel with Rushton turbine impeller are investigated using an insertion probe based on the telecentric transmitted light principle. High-resolution extracted from images convolutional neural network for image-analysis order to investigate influence of speed and phase fraction (up 50 vol.-%). addition, Sauter mean di...

Si les verbes et expressions dénommant l’acte sexuel en français académique sont rares (honorer une femme, plaisant, coïter, copuler didactiquess), il y a pléthore non conventionnel. En exposés quelques-uns, transitifs directs (baiser, sauter…) indirects (lui dégager écoutilles…), mais aussi intransitifs (tirer son coup…), avec un point de vue masculin dominant. L’argot se renouvelle : bouillav...

The momentum flux ratio (MFR) significantly affects the mixing characteristics and combustion efficiency of propellants in rocket engine injectors. spray three gas-centered swirl-coaxial injectors used a full-scale test were investigated according to change ratio. difference was analyzed through comparison with results using visualization quantification. cross-sectional shape droplet distributi...

This study focusses on investigating the effect of flow orientation global and local two-phase parameters under conditions. Flow visualization, pressure measurement, conductivity probe measurements are performed in a test facility made 50.8 mm inner diameter acrylic pipes with measurement. Characteristics regimes interfacial structures, frictional drop prediction vertical upward downward flows ...

We present a method for the numerical evaluation of 6D and 5D singular integrals appearing in Volume Integral Equations. It is an extension Sauter-Schwab/Taylor-Duffy strategy triangle-triangle interaction to tetrahedron-tetrahedron triangle-tetrahedron integrals. The general advantages these kind quadrature that they allow use different kinds kernel basis functions. They also work on curviline...
