Acceleration covariance in isotropic hydromagnetic turbulence

The present paper deals with the turbulent flow of an incompressible, viscous and conducting fluid which is isotropic, spatially homogeneous. The expression for acceleration covariance is derived. The obtained result shows that the defining scalars α(r, t) and β(r, t) of the acceleration covariance in MHD turbulence depend on the defining scalars of Q _ij , H _ij , Π _ij and S _{ik, j} .
