Description
| - The model of a passive scalar field advected by the compressible Gaussian strongly anisotropic velocity field with the covariance proportional to delta(t - t') vertical bar x - x'vertical bar(2 epsilon) is studied using the field theoretic renormalization group and the operator product expansion. The inertial-range stability of the corresponding scaling regime is established. The anomalous scaling of the single-time structure functions is studied and the corresponding anomalous exponents are calculated. Their dependence on the compressibility parameter and anisotropy parameters is analyzed. It is shown that, as in the isotropic case, the presence of compressibility leads to the decrease of the critical dimensions of the important composite operators, i.e., the anomalous scaling is more pronounced in the compressible systems. All calculations are done to the first order in epsilon.
