The present book discusses the heat transfer analysis on two-dimensional steady free or bio convection flow of Newtonian or non-Newtonian nanofluids over a stretching surface or cone surface or cylindrical surface. This book is divided into five chapters. The governing equations of the flow under consideration were solved with the appropriate boundary conditions by using well established numerical technique bvp4c method or Runge-Kutta-Fehlberg method of fourth fifth order. Chapter 1 intends to analyse the thermal optimization in magnetic materials based on the entropy generation in a mixed...
