Abstract: | An analysis is carried out to study the steady flow characteristics from a continuous flat surface moving in a parallel free
stream of non-Newtonian power law fluid. The constitutive equations of the fluid are transformed into dimensionless ones.
The velocity field is measured by Particle Image Velocimetry. Experimental results are obtained for the distribution of velocity.
The influence of wall velocity ratio parameter on boundary layer flow field is observed in the experiment. Dimensionless velocity
distribution and shearing stress distribution are obtained by post-processing experimental results. The effects of various
physical parameters like velocity ratio parameter and similarity variable on various momentum transfer characteristics are
discussed in detail and shown graphically. It is indicated that dimensionless velocity increases with velocity ratio parameter
and similarity variable, and that dimensionless shearing stress decreases with velocity ratio parameter and similarity variable. |
