Prediction of pressure drop in multiphase horizontal pipe flow [PDF]
, 2006 Empirical correlations were tested against reliable two phase pipe flow data for the prediction of pressure drop. Correlations are recommended for the prediction with stratified and annular type flows.

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

INFLUENCE OF VARIOUS OPTIONS TO BAFFLES SETUP ON AIR VELOCITY AND ITS UNIFORMITY IN A DRYING KILN [PDF]
Pro Ligno, 2015 In this study, an experimental-based comparative analysis among different options to the baffles settup in a drying kiln was carried. The experiments consisted in measuring the air velocity in different points located at the outlet face of stacks.

Verallgemeinerung der Stromfunktionsmethode auf drei Dimensionen
Meteorologische Zeitschrift, 1995 Es wird gezeigt, daß die "Stromfunktionsmethode ", die bisher nur für die Lösung zweidimensionaler inkompressibler Strömungsprobleme gebräuchlich ist, auf plausible Weise auf drei Dimensionen verallgemeinert werden kann.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
Advanced Engineering Materials, EarlyView.We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Design of Extrusion Die for Medical Multi-lumen Tube Using Inverse Extrusion Simulation and Optimization [PDF]
한국정밀공학회지The design of the extrusion die significantly affects both the extrusion process and the quality of multi-lumen tubes. Traditional design methods that rely on trial and error tend to increase manufacturing time and costs while diminishing product quality.

Advanced Engineering Materials, EarlyView.This study explored how effective nickel aluminide coatings are obtained in providing oxidation resistance applied to the Inconel 738 alloy, modeling with diffusion models. In the present study, kinetics and thermal behavior of the Inconel 738 alloy were studied by the low‐temperature thermoreactive aluminizing process, which was carried out at 625°C ...
