A wake/boundary layer interaction model was derived based on negative jet effect of wake transport in turbomachinery

in consideration of the influences of outer boundary layer's viscous force on boundary layer development.Then

the relationship between pressure rise and momentum thickness was established.An experiment was designed to verify this model about effect of wake passing frequency on compressor pressure rise at fixed wake depth and wake width.Comparison of model and experimental results indicates that: (1) The model can be used to predict the effect of wake passing frequency on compressor pressure rise effectively. (2) The key factor of wake/boundary layer interaction is local pressure gradient that changes with wake

which leads to pressure rise finally.
