Dissipation model based on the paper: Generalized Viscous Vortex Model for Application to Free-Vortex Wake Calculations,Bhagwat and Leishman (2002) The apparent viscosity coefficient is 'a1' known as Squire's app. viscosity parameter and this allows the dissipation to be dependent on the vortex strength The apparent viscosity is kinematic viscosity plus the turbulent viscosity (a1*|gamma|)) a1 has to be O(1e-4) for rotary wings (usually set to 2e-4) and O(1e-5) for fixed wings
