Unsteady Flow Due to the Stretching/Shrinking Surfaces
The preceding three chapters have strictly been restricted to the cases of steady viscous flows due to the motion of continuous surfaces. The similarity criterion has been established for such flows regarding the rectangular and axisymmetric flow geometries. So far, attention has not been given to the unsteady flows of this category regarding the existence of self-similarity, in this book. This chapter is particular to the unsteady flows regarding the determination of similarity criterion in the planar and axisymmetric flow situations.
