The bridge ‘hydraulics analysis and design’ could be substantially enhanced using advanced commercial Computational Fluid Dynamics (CFD) software and powerful parallel computing resources. The objective of the present study is to validate STAR-CD commercial CFD software for the bridge hydraulics research. This study simulates limited scaled experimental data conducted elsewhere for bridge flood...

amniotic fluid volume (afv) is one of the important parameters in the assessment of fetal well-being. the ability of ultrasound measurements to represent the actual afv is unproven. this study was undertaken to compare correlation of conventional amniotic fluid index (afi) and radial amniotic fluid index (rafi) as a new method with actual fluid volume on phantom. as an experimental study, 10 to...

The formation of discrete water clusters in polymer electrolyte fuel cell gas diffusion layers (GDL) can lead to increased resistance for oxygen transport the catalyst layer. This study investigates effect MPL crack propagation on cluster development a X-ray computed tomography (CT) microstructure using volume-of-fluid method (VoF). VoF calculation was compared operando CT data by voxel matchin...

Multiphase flows exist widely in daily life and many industrial processes, such as soap bubbles, rain drops, internal combustion engines, thermal spray coating, and ink-jet printing, et al. In the numerical study of multiphase flows with clear interfaces, it is extremely important to accurately track the interfaces. Many numerical methods have been developed to treat the interface, including Le...

This paper presents optimisation of the geometry aircraft air–oil separator (AAOS) performed to improve device performance. For this type, most important operating parameters are oil quality, efficiency and pressure drop. In order understand relationships between geometric their impact on operation, an analysis was conducted using Response Surface Method (RSM). The made based results numerical ...

In this paper, the unsteady flow of two immiscible fluids with heat transfer is studied numerically with a modified cubic B-spine Differential Quadrature Method. Generalized Couette two immiscible dusty (fluid-particle suspension) and pure (Newtonian) are considered through rigid horizontal channels for three separate scenarios: first non-porous plates heat transfer, second porous uniform s...
