摘要：

The intention of this analysis is to analyse the heat transfer impact on MHD ferrofluid flow over a shrinking sheet. This study is carried out under the knowledge of frictional heating, Biot number and thermal radiation. With the assist of suitable similarity transformations, the governing equations are transmuted into coupled nonlinear ODE's and then numerically solved by R.K. Fehlberg Technique. For this study, we considered the water - Fe3O4 ferrofluid. The behavior of sundry physical parameters on fluid velocity, temperature, skin friction coefficient and local Nusselt number are discussed and presented through plots and tables. Through this investigation, we found that the magnitude of fluid velocity enhances with rising values of volume fraction of nanoparticles. Also, it is found that the Eckert number has tendency to reduce the rate of heat transport. © 2017 Trans Tech Publications, Switzerland.
