This paper describes how an industrial-scale real-time computing platform, namely the Honeywell TDC3000, has been incorporated into the undergraduate process control course at Arizona State University. The mixing tank dynamics and gas oil furnace control experiments described in this paper are among eleven laboratory exercises developed for this course which provide students with unique insight...
We prove the existence of invariant curves for a T – periodic Hamiltonian system which models a fluid stirring in a cylindrical tank, when T is small and the assigned stirring protocol is piecewise constant. Furthermore, using the Numerical Analysis of the Fundamental Frequency of Laskar, we investigate numerically the break down of invariant curves as T increases and we give a quantitative est...
— Seven important variables having profound impact on the ability of a mixing tank to suspend particles have been investigated using computational fluid dynamics (CFD) technology. The results obtained from this study can be applied across a broad range of industries such as the chemical, biochemical, petrochemical and mineral processing industries. Finally, a design template incorporating the o...
Thermal-energy storage systems consisting of multiple tanks allow the implementation thermocline-control methods, which can reduce drop in outflow temperature during discharging and increase volumetric density utilization factor. Multi-tank based on extraction mixing methods were assessed using simulations assuming fluvial rocks as material compressed air heat-transfer fluid. For adiabatic cond...
Characterization of Mixing in a Simple Paddle Mixer Using Experimentally Derived Velocity Fields Douglas Bohl 1 , Naratip Santitissadeekorn, Akshey Mehta 1 , and Erik Bollt 1 Department of Mechanical and Aeronautical Engineering 2 Department of Mathematics Clarkson University Potsdam, NY Abstract The flow field in a cylindrical container driven by a flat bladed impeller was investigated using P...
Agitating liquids in an unbaffled surface aeration tank leads to the formation of a vortex in the region of the impeller shaft. The types and characteristics of the vortex govern the process phenomena of a surface aeration tank. In the present work, experimental results and empirical correlations have been obtained to relate the vortex depth to a number of physical factors. Experiments have bee...
In this paper, a numerical study of a chaotic mixing process that involves a highly viscous fluid is presented. The investigated mixer is composed of two circular rods maintained vertically inside a cylindrical tank. The tank and the rods are heated and can rotate around their revolution axis. Chaotic flows are obtained by imposing a temporal modulation of the rotational velocity. Unsteady equa...
The TITUS, Tokai Intermediate Tank for Unoscillated Spectrum, detector, is a proposed Gd-doped Water Cherenkov tank with a magnetised muon range detector downstream. It is located at J-PARC atabout 2 km from the neutrino target and it is proposed as a potential near detector for the HyperKamiokande experiment. Assuming a beam power of 1.3 MW and 27.05×10 protons-on-target the sensitivity to CP ...
The dissipation rate of turbulent kinetic energy () and shear rate (γ) are the key process parameters for mixing in surface aerators. At constant dynamic variables (rotational speed), both and γ are greatly affected by the geometric parameters (impeller diameter, cross-sectional area of the tank, liquid height, rotor blade length and immersion height). By doing numerical computation by VISIM...
