Summary: We consider the self-similar wall jet over an impermeable resting plane surface (Glauert jet). Through an analytic technique to solve nonlinear problems, namely the homotopy analysis method, we obtain an explicit series solution for the Glauert-jet problem. This series solution converges efficiently to the closed-form solution found by Glauert in the whole region \(0 \leqslant \xi < + \infty\) . In the frame of the homotopy analysis method, it is shown that the convergence region of the explicit series solution may be adjusted to obtain more accurate results.
