Jet Mixing Enhancement Using AI

Almost all country around the world always focus on the issue of energy that play an important role on economic development for the country.Jet can efficiently improve fuel utilization efficiency,it is indispensable to enhance the development of engine of rocket and aerocraft.The mixing efficiency of fuel and air can increase on combustion chamber by jet technique that can decrease noise and produce strong impetus better.Hence,it is basic to learn jet for supplying cleaner fuels and reducing noise of engines.The article is aiming to enhance jet mixing by using Artificial intelligence(AI)control system.My work is aiming to use the excitation of minijets to enhance the centerline axial mean velocity decay and jet mixing of main jet.The article itself mostly concern one project that one minijet how to influence the performance of main jet.The research using AI control system has surveyed the results that minijets with different mass flow rate ratio influence the performance of main jet under different Re _D=8000,13300,2000.AI control system can randomly produce a great number of individual of control law and then it can find out that excitation frequency of minijet,duty cycle,mass flow rate ratio of minijet and the optimal cost function J.Furthermore,researching the effects what different number of minijets influence the performance of main jet.The Re _D of main jet equal to 8000.Include three conditions,such two-minijets,three-minijets,six minijets,and AI control system and Improved AI control system.Compared the difference of performance of main jet under the two system.Achieved the optimal control and it closely related to J.
