A model of scalar turbulent advection in compressible flow is analytically investigated. It is shown that, depending on the dimensionality d of space and the degree of compressibility of the smooth advecting velocity field, the cascade of the scalar is direct or inverse. If d . 4 the cascade is always direct. For a small enough degree of compressibility, the cascade is direct again. Otherwise it is inverse; i.e., very large scales are excited. The dynamical hint for the direction of the cascade…

The existence of additional regimes, which could not be found using the direct perturbative approach of the previous work, are explored, and the crossover between different regimes is analyzed to determine them near the special value of space dimension 4 in the framework of double y and ɛ expansion.
