A two-fluid model was adopted to simulate the three-dimensional gas-liquid flow in an aeration tank. During the modeling, different process parameters of aeration tank was simulated, and the gas-liquid flow behavior in aeration tank was analyzed. The CFD simulation and PIV measurement were both used to analyze the flow field in the aeration tank. The result shows that with the increasing of the depth,...
In this paper, we present a systematic approach inspired from the ergodic theory of dynamical system for the optimal control of complex fluid flows. The infinite dimensional Navier Stokes equation describing the complex fluid flow is first reduced to a finite set of coupled ordinary differential equations. We utilize Proper Orthogonal Decomposition techniques to obtain a reduced order model. The linear...
