Fluids dynamics - tornado modeling

I was wondering if someone could give me an advice about the next problem: I am modeling a tornado in which an explosion in its axis occurs. In the initial conditions it is supposed that the tornado is rotating with an angular velocity /omega and and there is a difference of pressures inside and outside the tornado. When the explosion occurs the pressure difference falls and the tornado must start to expand and its angular velocity is supposed to fall because of the conservation of angular momentum. My problem is, that even if a put the same pressure inside and outside of the tornado at the beginning, it is not observed that the rotational energy of the beginning becomes kinetical energy in the radius direction.
I would really appreciate some help on this!!!!
Best Regards,
Oscar
