Fourth-order statistical moments of the velocity gradient tensor in homogeneous, isotropic turbulence
Juan Hierro, César Dopazo
A compact expression of fourth-order statistical moments of the velocity gradient tensor in homogeneous, isotropic, incompressible turbulence is obtained as a function of its invar…
