The strained-spiral vortex model of turbulent fines scales given by Lundgren [Phys. Fluids 25, 2193 ( 1982)] is used to calculate vorticity and velocity-derivative moments for homogeneous isotropic turbulence. A specific form of the relaxing spiral vortex is proposed modeled by a rolling-up vortex layer embedded in a background containing opposite signed vorticity and with zero total circulation at infinity. The numerical values of two dimensionless groups are fixed in order to give a… CONTINUE READING
