Abstract :
The present study aims to investigate time-dependent two-dimensional
Sakiadis ow of quiescent uid. This ow is induced by stationary at plate through uniform free-stream (Blasius ow). The variable conductivity and viscosity ratio parameters
as well as non-linear chemical reaction were taken into account in the mathematical
equations. Similarity variables were employed in the governing transport expressions to
convert them into the ordinary differential system. The transformed system is numerically
computed using Runge-Kutta scheme and based on shooting criteria. The results regarding
concentration, velocity, and temperature distributions were also studied through plots.
Moreover, mass and heat transfer rates and friction factor were discussed in detail.
According to the ndings, the constraint of chemical reaction slowed down the rates
of friction factors and heat transportation in the case of the Sakiadis-Blasius
ow and enhanced the mass transportation rate in both cases. In addition, the rate of mass
transportation was smaller in Sakiadis ow than that of Blasius ow. The obtained results of the rate of heat transfer were in excellent agreement with those from the literature.
