“…The heat exchange aspects with estimation of the Reynolds and Nusselt numbers are discussed in Wang et al [10]. The supersonic wind tunnels and turbine devices with settling chambers are of wide interest to many researchers e Bhoi and Suryanarayana [11] attempted to predict the pressure characteristics, Rajani et al [12], discussed temperature effects in testing aerodynamic forces, Silva et al established a model for the Reynolds number test, [13]. In Chong et al's paper [14], settling chambers play a significant role in achieving a quiet, low turbulent open jet blow downstream the wind tunnel.…”

“…The controller must operate at different stagnation pressures and Mach numbers and has to be robust to accommodate the varying pressure and mass flow requirements safely. New concepts for control are under implementation with the goal of reducing transition phase and overall loads on the models [4,5].…”

The application of fuzzy logic controllers (FLCs) to the control of nonlinear processes, typically controlled by a human operator, is a topic of much study. In this paper, the design and application of a FLC is discussed to control the plenum chamber temperature for a blowdown supersonic wind tunnel (BSWT) with the aim of achieving the accurate and desired results. In this regard, first, a nonlinear mathematical model of special BSWT is developed in Matlab/Simulink software environment. Next, an artificially intelligent controller is designed using fuzzy logic approach. For this purpose, a proportional-derivative FLC (PD-FLC) system is developed in the Simulink toolbox to control the plenum stagnation temperature using a heater upstream of the plenum chamber. Finally, the system simulation results inside of the temperature and pressure controllers in comparison with the experimental run are presented. The results for Mach 2.5 blowdown run show the great performance of the Wind Tunnel Simulator Model and its temperature controller system.
