Abstract:
Similarity solution plays a vital role for the reduction of variables (depcndents or
independents) when the questions of partial differential equations arise in dealing with
the boundary value problems. The present study deals with the possible similarity
solutions of unsteady Iaminor boundary layer free convection flow around a vertical
curvilinear surtaec. The froc parameter method is introduced. Then the pertinent
ooundary layer partial differential equations under a suitable transformation are reduced
to a set of ordinary dilTercntiai equatiollS. These simultaneoi.L~transformed ordinary
differential equations with proper boundary conditions are solved numerically using
Nachlshcim-Swigert iteration technique and Runge-Kulla shooting method. The results
arc compared with an other relevant works for special situations. The non-dimensional
skin-friction factors (=fw,(O),r.2(O») and heat trans/ee co-efficient (=qw(O)) arc
displayed and shown graphically for some values of the controlling parameters by using
the Software FORTRAN 77 and TECPLOT.
