Following Deissler’s approach, the decay of MHD turbulence at times before the final period for the concentration fluctuations of a dilute contaminant undergoing a first order chemical reaction in a rotating system for the case of multi-point and multi-time is studied. Here two and three point correlations between fluctuating quantities have been considered and the quadruple correlations are neglected in comparison to the second and third order correlations. The correlation equations are converted to spectral form by taking their Fourier transforms. Finally, integrating the energy spectrum over all wave numbers, the solution is obtained and this solution gives the Decay law of magnetic energy for the concentration fluctuations before the final period in a rotating system for the case of multi-point and multi-time.
Key words: MHD turbulence, first order reactant, rotating system, decay before the final period, , ,
