Abstract Merk's series solution to the momentum equation for steady
two-dimensional or axisymmetrical constant-property laminar
boundary layer flow was examined. Solutions were obtained to the
differential equations associated with the second term in the series.
Calculations using this series were made, and it was found to be unsatisfactory
because the second term diverges near the point where
the first term becomes imaginary. This phenomenon occurs significantly
earlier than the actual separation point in every case studied.
A new, formally exact series solution for momentum, heat
and mass transfer in steady two- dimensional or axisymmetrical
constant-property laminar boundary layers was developed. An approximation
was introduced to simplify momentum transfer calculations,
and an additional approximation was used for heat and mass
transfer. Calculations using this method for momentum transfer
with several different external velocity distributions and with both low and high rates of injection at the surface compared well with
exact solutions. In every case studied, the present method was significantly
more accurate than other approximate methods. Heat and
mass transfer calculations compared well with experimental data
taken from several investigations. Extensive tables of functions associated
with the present method have been compiled.
