The effect of plasma rotation on suppression of magnetohydrodynamic(MHD) turbulence is studied using a turbulent dynamo model.This dynamo model consists of the equations for the turbulent MHDenergy, its dissipation rate, and the cross helicity, which aresolved numerically. The temporal evolutions of the turbulent MHDenergy and the turbulent cross helicity are compared between stateswith and without poloidal plasma rotation. It is shown that theturbulent MHD energy is greatly suppressed through the turbulentcross-helicity effect in the presence of poloidal plasma rotation.The cross-helicity production mechanism is also discussed.
