This book provides a supplementary note on a new emerging area of nanotechnology. It explores about the Nanofluid which is the active research area. It provides a numerical solution of some problems on a stretching sheet and a vertical plate. The book also presents the boundary layer flow and heat transfer analysis of a stretching sheet by considering different types of surface boundary condition such as convective surface condition. It also discusses the slip boundary condition for velocity, temperature and concentration profiles. It mainly focuses on heat transfer and boundary layer flow of nanofluids. The book would be a useful reading material for students of Applied mathematics and Engineering disciplines.
