In many applications involving chemical reactions, the efficiency of the process is dependent on the ability to control the temperature of the system. In case of an exothermic chemical reaction, maintaining the desired temperature of the system becomes difficult when the reaction heat is released rapidly once an activation temperature is reached. In this study, a multi-platform coupled simulation using ANSYS-FLUENT and MATLAB/Simulink was established to simulate the chemically reacting flows coupled with different control algorithms. To demonstrate this system, a simple test case was created. A fixed-bed reactor was modelled in ANSYS-FLUENT and was coupled with two different control algorithms including Proportional-Integral-Derivative Control (PID) and Model Predictive Control (MPC) compiled in Simulink. The two software packages exchanged data via a shared file system, thus allowing each package to run on a separate computing platform. This multi-platform coupled simulation framework enabled this study to investigate the ability of different control techniques to maintain the temperature of the system as a function of reaction rate. The results verify the feasibility of using such platform to test different control algorithms for a temperature control problem.
