Scientific paper

Some locally rotationally symmetric Bianchi type-I cosmological solutions for a cloud string with bulk viscosity are presented. In the first case, an equation of state rho = klambda and the relation between metric potentials R = ASn are considered, and the solution represents shearing non-rotating model with the bulk viscosity zetaproptorho1/2, where rho is the rest energy density of the cloud of strings with particles attached to them, lambda is the tension density of the cloud of strings, zeta is the coefficient of the bulk viscosity, R and S are only the functions of time t, while A and k are constant. In the second case, the constant coefficient of bulk viscosity is considered.
