Abstract This work deals with the application of open-source computational fluid dynamics (CFD) code MULTALL to analysis tube-axial fans. The has been widely validated in literature for high-speed turbomachine flows but not applied yet low-speed tutbomachines. aim this is assess degree reliability as a tool simulating internal flow industrial axial-flow fan rotors. To end, predictions steady-st...

Title of Thesis: FLUID AND PARTICLE DYNAMICS IN AN AEROSOL VIRTUAL IMPACTOR Marwan L. Charrouf, Master of Science, 2004 Thesis Directed by: Professor Richard V. Calabrese Department of Chemical Engineering The collection and characterization of chemical and biological aerosols is essential to many areas of particle research such as toxicological studies, pollutant sampling, and biohazard assess...

An extreme form of pipelining of the Piecewise-Parabolic Method (PPM) gas dynamics code has been used to dramatically increase its performance on the new generation of multicore CPUs. Exploiting this technique, together with a full integration of the several data post-processing and visualization utilities associated with this code has enabled numerical experiments in computational fluid dynami...

I describe a method, particularly suitable to implementation by computer algebra, for the derivation of low-dimensional models of dynamical systems. The method is systematic and is based upon centre manifold theory. Computer code for the algorithm is relatively simple, robust and flexible. The method is applied to two examples: one a straightforward pitchfork bifurcation, and one being the dyna...

this paper aims to study a generalized double sinh-gordon equation, which appears in several physical phenomena such as integrable quantum field theory, kink dynamics and fluid dynamics. lie symmetry analysis together with the simplest equation method is used to obtain exact solutions for this equation. moreover, we derive conservation laws for the equation by using two different approaches, na...

Why: Due to the long processing time associated with Monte Carlo, it is advisable to adopt a faster alternative forward model with comparable accuracy. FD, implementing the diffusion equation, offers greater computational efficiency, but at the cost of modeling accuracy. The low scattering properties of the Cerebral Spinal Fluid (CSF) filling the space between the brain and the skull has been o...

The permeable reactive barrier (PRB) technology is an in-situ approach for remediating groundwater contamination that combines subsurface fluid flow management with a passive chemical treatment zone. Removal of contaminants from a groundwater plume is achieved by altering chemical conditions in the plume as it moves through the reactive barrier. Because the reactive barrier approach is a passiv...

This paper introduces mdFoam+, which is an MPI parallelised molecular dynamics (MD) solver implemented entirely within the OpenFOAM software framework. It is open-source and released under the same GNU General Public License (GPL) as OpenFOAM. The source code is released as a publicly open software repository that includes detailed documentation and tutorial cases. Since mdFoam+ is designed ent...
