Analysis of the self-similar solutions of a generalized Burgers equation with nonlinear damping

The nonlinear ordinary differential equation resulting from the self-simila r reduction of a generalized Burgers equation with nonlinear damping is stu died in some detail. Assuming initial conditions at the origin we observe a wide variety of solutions (positive) single hump, unbounded or those with a finite zero. The existence and nonexistence of positive bounded solutions with different types of decay (exponential or algebraic) to zero at infini ty for specific parameter ranges are proved.
