Collaborative Optimization of Aerodynamic Resistance and Aerodynamic Noise for Spanwise Waviness Bars
摘要
Abstract
The spanwise waviness bars are known to have good drag and noise reduction effects,but there is a lack of structural parameter optimization design methods.To address the problem,a multi-disciplinary collaborative optimization ap-proach was employed to co-optimize the wavelength and corrugation amplitude structural parameters of the spanwise wavi-ness bars with aerodynamic drag and aerodynamic noise as objectives.A numerical simulation model of the flow field and sound field of the bar was established using the Realizable k-ε model and SNGR model.Combined with the numerical simu-lation results of Latin hypercube sampling and sample point structure,a Kriging surrogate model based on genetic algorithm was constructed to optimize the resistance value and aerodynamic noise value.Using co-optimization algorithm,dual-objec-tive collaborative optimization was carried out.The optimal spreading corrugated structure parameters were found and veri-fied by simulation.The research results indicate that the aerodynamic noise and drag of the spanwise waviness bar cannot be simultaneously optimized to the best values.After dual-objective collaborative optimization,the drag coefficient of the mod-el decreases by 1.59%of the initial model of 1.743,while the total sound pressure level decreases by 4.66%of the initial model of 103.64 dB,which demonstrates a balance between noise reduction and drag reduction effects.关键词
