Abstract

Using Deissler’s method we have studied the decay of temperature fluctuations in dusty fluid homogeneous turbulence before the final period and have considered correlations between fluctuating quantities at two- and three- point. The equations for two and three point correlation in presence of dust particles is obtained and the set of equations is made to determinate by neglecting the forth order correlation in comparison to the second and third order correlations. For solving the correlation equations are converted to spectral form by taking their Fourier transform. Finally integrating the energy spectrum over all wave numbers, the energy decay law of temperature fluctuations in homogeneous turbulence before the final period in presence of dust particle is obtained.
