Calculation of water droplet impingement characteristics on rotating fairing of aero-engine
摘要
Abstract
As one of the critical components of aircraft engine icing,the water droplet impingement characteristics on the rotating fairing surface directly influences the subsequent icing state.To investigate the water droplet impingement behavior under different operating conditions,a three-dimensional water droplet impingement model for the rotating fairing of aero-engine was established by using the Euler method and single rotating coordinate system.The water droplet impingement characteristics of the rotating fairing under stationary and rotating conditions were simulated respectively.The results show that under stationary conditions,as the freestream Mach number increases,both the water droplet collection coefficient and impingement area exhibit significant growth;compared to single-diameter droplets,when considering the Langmuir-D distribution of water droplets,the collection coefficient at the stagnation point decreases,while the impingement zone increases and the downstream collection coefficient also slightly increases.Under rotating conditions,the rotational speed has negligible effects on droplet impingement characteristics due to the streamlined aerodynamic profile of the rotating fairing.关键词
