BVF

Aerodynamic optimization method of transonic fan rotor based on BVF

跨声风扇转子的BVF气动优化方法

The aerodynamic optimization of a transonic fan rotor was implemented by controlling the BVF ( boundary vorticity flux) distribution on rotor blade. A novel objective function of torque associated with BVF was used to optimize the blade configuration.

将加功量作为目标函数并结合边界涡量流BVF（Boundary Vorticity Flux）这个诊断因子，对某高性能跨声风扇转子进行了优化。

Since BVF has very important influence on instability in the moist case, we have looked for the expression of BVF which is more appropriate for the real moist case. Thus Ri is modified, so that we can estimate instability in the moist process.

既然BVF在湿过程中对不稳定有非常重要的影响，我们寻找了更符合湿过程中实际情况的BVF表达式，以对Ri进行修正，从而更好地判断湿过程的不稳定。
