The flow field of rotating channel which is a cylindrical combustion of rotating solid rocket motor with mass injection from wall surface was investigated. Simplified Euler Equation was solved using analytic methods. Analytical solution of the rotating channel was obtained without considering viscosity. On the basis of this, the tangential momentum equation considering viscosity modification was solved using matched asymptotic expansions of perturbation method, and the analytical solution was obtained. The result shows that tangential velocity distribution has the characteristics of combination vortex. The relationship among vortex core radius and injection Reynolds number and rotation revolution was analyzed. The regularity of the combination vortex was obtained under the condition of compressible modification.
