Fig. 6

a The mass growth within the LEV along the span of a rotating wing is an approximately linear distribution while b the circulation growth along the span of a rotating wing is growing faster. Both the mass m and the circulation \(\Gamma ^{*}\) distributions are presented in function of the span position \(z^{*}\) and in function of the time, or the equivalent revolution angle \(t^{*} = \theta\). The figure presents the \(Re=2500\) case, but the behaviours for the \(Re=1000\) are similar
