Nonlinear Effects of Actuator Induced Turbulence in a Controlled Flow System

We develop and apply a technology for the automatic detection and real-time mitigation of accidental or deliberate hazardous releases in infrastructure systems. A prototype is used at laboratory scale to demonstrate the detectability and controllability of hazardous releases in real time. The model provides optimal operation scenarios for computer controlled bleed valves mounted on the channel walls that allow blowing and suction of ambient fluid or injection of counteracting chemicals. We present some computational and laboratory experiments that demonstrate the potential for nonlinear flow patterns induced by boundary flowing and suction.
