  Kazantsev  model for 2.5D  flows  K. Seshasayanan*  and A. Alexakis E´ cole Normale Supe´rieure – Paris  We study the dynamo instability of the Kazantsev model for a 2.5D flow with the flow defined by (u(x, y, t), v(x, y, t), w(x, y, t)).  We  are interested in dynamo instability  for nonhelical flows.  We  derive  here the governing equations for the second order magnetic field correlation function. We then study the growth rate of the dynamo instability  as a function of the control parameters. We compare our results of the analytical calculation with numerical simulation of the model flow and with other time correlated flows.
