Title
Some unsteady flows over a stretching sheet: Analytic solution for viscous and second grade fluids,Used
Delivery time: 8-12 business days (International)
The partial differential equations arising in the study of nonNewtonian fluids offer many challenges not only to physicists and numerical analysts but also mathematician alike. Particularly the studies regarding the unsteady flows due to a stretching sheet is very scarce in the literature. Much attention has been given to the steady flow problems. Few attempts have been made regarding the unsteady flows. The main aim here is to develop the analytic series solutions using homotopy analysis method. One important aspect of these solutions is that these solutions are valid for all the dimensionless time values as most of the numerical solutions does not. In this particular book we have emphasized on the viscous and second grade fluids both for linearly and radially stretching sheets.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
