This book is useful for UG, PG and Researchers in the area of fluid mechanics particularly mathematical modelling of nano particles.This book is divided into two chapters.First chapter deals with 1)Brief introduction to Nanofluids, various boundary conditions, Thermo physical parameters and its application. Second Chapter deals with 2)heat transfer characteristics of Casson nanofluid flow over a rotating cone in a rotating frame filled with water based CoFe2O4 nano particles. Heat flux conditions and wall temperature conditions are very important in controlling of up and down heat transport phenomena in industrial as well as engineering application.
