Abstract A computational fluid dynamics simulation is done for comparative study from the pumping effect on four surfaces of stirred tank. The flow field generated by one-stage and bi-stage six-bladed Rushton turbine in unbaffled square tank was studied. Reynolds-averaged Navier-Stokes equation with steady-state multi-reference frame approach (MRF) used to simulate hydrodynamic turbulent viscos...

Lagrangian trajectories obtained through 3D Particle Tracking Velocimetry (3D-PTV) measurements have been used to visualize the flow field of Newtonian and non-Newtonian fluids in a flat-bottomed vessel. The vessel, diameter T=180 mm, was equipped with 6-blade Rushton turbine D=T/3 four baffles width b=T/10. experiments were carried out transitional regime (73≤Re≤1,257). velocities acceleration...

The purpose of this article is to provide mathematical insights into the results of some Monte Carlo simulations published by Tolhurst and colleagues (Clatworthy, Chirimuuta, Lauritzen, & Tolhurst, 2003; Chirimuuta & Tolhurst, 2005a). In these simulations, the contrast of a visual stimulus was encoded by a model spiking neuron or a set of such neurons. The mean spike count of each neuron was gi...
