The prediction of transonic loading advancing helicopter rotors [PDF]

Two different schemes are presented for including the effect of rotor wakes on the finite-difference prediction of rotor loads. The first formulation includes wake effects by means of a blade-surface inflow specification.

Dynamic Equivalence Modeling of Short-Circuit Faults in Wind Farms Considering Wake Effects

Shanghai Jiaotong Daxue xuebao
Fast and accurate analysis of the short-circuit characteristics of large wind farms has important engineering application value, and the short-circuit characteristics of wind farms under the influence of the wake effect vary greatly.

Viscous wing theory development. Volume 1: Analysis, method and results [PDF]

Viscous transonic flows at large Reynolds numbers over 3-D wings were analyzed using a zonal viscid-inviscid interaction approach. A new numerical AFZ scheme was developed in conjunction with the finite volume formulation for the solution of the inviscid
