Abstract: A method of solution for laminar channel flow is established using the von Mises transformation followed by the separation of the main flow velocity into amplitude and profile functions. The known boundary conditions on the latter enable a generalized solution that yields, through parametric relation between auxiliary parameters, a system of ordinary differential equations for the velocity amplitude and the pressure. The result is a powerful semianalytical method which is very easy to implement for a variety of internal flow configurations. The method is, in essence, a downstream general solution which may be extended upstream to the singular limit of a uniform main flow velocity distribution at the channel entrance. The regular solution for uniform initial velocity distribution cannot thus be obtained. Comparisons with other solutions show only qualitative agreement, whereas agreement with experimental results is remarkably good.
