Particle-laden flow around an obstacle in a square pipe: experiments and modeling

Simulation of a 2d Channel Flow around a Square Obstacle

Results for time-dependent, viscous, incompressible flows were investigated using the lattice-Boltzmann (BGK) automata. The decay of a synthetic turbulent flow field and the time evolution of an initial vortex were simulated for validation purposes. The focal point was the investigation of the instationary flow around a square obstacle in a twodimensional channel for a range of Reynolds numbers...

Design, Modeling and Experiments of An In-pipe Magnetostrictive Impact Drive Mechanism

This paper presents a magnetostrictive in-pipe impact drive mechanism (IDM). To estimate the output performances of the IDM, a dynamics model was developed based on the magnetostrictive material constitutive model and mechanical model of the IDM. Therefore, an experimental system has been built to test the motion performance of IDM. Simulation and experimental results illustrate that the propos...

development of an explicit eulerian method for treating particle laden turbulent flow in dust collectors

Constrained flow around a magnetic obstacle

Many practical applications exploit an external local magnetic field – magnetic obstacle – as an essential part of their construction. Recently, Votyakov et al. (2007) have demonstrated that the flow of an electrically conducting fluid influenced by an external field can show several kinds of recirculation. The present paper reports a 3D numerical study whose some results are compared with an e...
