The fluid flow and heat transfer in a three-dimensional microchannel filled with Al2O3- water nanofluid is numerically investigated. The hybrid scheme is used to discretize the convection terms and SIMPLER algorithm is adopted to couple the velocity and pressure field in the momentum equations. The temperature fields, variation of horizontal velocity along the centre line of the channel, a...

Spacers are used in spiral wound and plate and frame membrane modules to create flow channels between adjacent membrane layers and mix fluid within the flow channel. Flow through the spacer has a significant beneficial impact on mixing and resulting mass transfer rates but is accompanied by an undesirable increase in pressure drop. Computational Fluid Dynamics (CFD) is a common tool used to eva...

Observations of six luminous blue compact galaxies (BCGs) and two star forming companion galaxies were carried out with the CIGALE scanning Fabry-Perot interferometer attached to the ESO 3.6m telescope on La Silla. The observations were made in the Hα emission line which is prominent in BCGs. A velocity sampling of 5 km/s and a pixel size of 0.9 arcseconds were used. In this paper we present th...

1. Abstract The effective application of shape optimization procedures based on the FEM to engineering problems requires a fully integration of concepts and sofwate modules for geometric modelling, finite element analysis, sensitivity analysis, minimization procedures, mesh generation, updating and distortion control. In this sense, the central concept for the connection and communication among...

Acoustic tomography of the atmospheric surface layer (ASL) is based on measurements of the travel times of sound propagation between sources and receivers which constitute a tomography array. Then, the temperature and wind velocity fields inside the tomographic volume or area are reconstructed using different inverse algorithms. Improved knowledge of these fields is important in many practical ...

Fluids research often involves developing theories about the complex relationships between multiple scalar and vector quantities. We discuss strategies for effectively visualizing co-located vector fields, enabling the key physical structures of one vector field to be clearly understood within the context of a related vector field. We describe the range of effects that can be obtained by combin...

The application of tomographic techniques for the study of vector fields has been demonstrated only in the last few years. We show its potential for remote sensing of plasma vector fields such as the fluid velocity v and the magnetic field B using Doppler and Zeeman spectroscopy. Simulations suggest the possibility of time-resolved reconstruction of ion velocity flow fields and poloidal magneti...
