This paper presents an approximate solution of the second-order boundary layer equations for a two-dimensional laminar wall jet of an incom- pressible fluid over a curved surface. Applying the small perturbation method with a small parameter expressed as a power of the streamwise coordinate, similar and non-similar velocity pro- files are calculated along curved walls when the local curvature is proportional to xm-3/4, in which m=0 corresponds to the hitherto treated case of the similar flow, m=3/4 to the flow over a circular cylinder and m>1 to the flow accelerated downstream in the case of convex surfaces. The variation of the velocity profile, the total entrainment rate, the skin friction and the surface pressure as a function of curvature or the exponent m are indicated.
