Researchers Optimize Air Supply Uniformity in Airliner Cockpits Using Adjoint Method and Genetic Algorithm

Strategic Insights -

Research conducted by Zhengwei Long and colleagues at Tianjin University in China has led to a significant improvement in the uniformity of air supply in airliner cockpits. The research focused on optimizing the air supply system using a hybrid optimization strategy that combined the adjoint method and genetic algorithm. This approach resulted in a 68.6% improvement in air supply uniformity after optimization, ensuring that the actual air supply effect is consistent with the design and avoiding discomfort caused by excessively high local velocities.
