摘要
Abstract
Simplified pre-swirl system and flow field nearby receiver hole under typical conditions were analyzed.Based on the consequences,circumferential velocity ratio model of receiver hole was constructed.CFD analysis was carried out through a series of typical conditions.Result of comparing to CFD data demonstrates the model prediction is effective.Current study results show that:based on flow pattern inside receiver hole,this area was divided into 3 regions,influencing factors including swirl ratio,length-radius ratio and attack angle,the model to predict circumferential velocity ratio was proved to be enough accuracy.In contrast to the original receiver hole component model,that modi-fied by circumferential velocity ratio makes better coincide with CFD data.关键词
