DTM for Nanofluids and Nanostructures Modeling

Nanofluids are produced by dispersing the nanometer-scale solid particles into base liquids with low thermal conductivity such as water, ethylene glycol, oils, etc. The presence of the nanoparticles in the fluids noticeably increases the effective thermal conductivity of the fluid and consequently enhances the heat transfer characteristics. Therefore, numerous methods have been taken to improve the thermal conductivity of these fluids by suspending nano/micro-sized particle materials in liquids. Also nanostructures such as nanobeam, nanotube, etc., have many applications in mechanical engineering. This chapter focuses on the solving problems in this field and contains the following sections: 5.1 Introduction 5.2 Nanofluid in Divergent/Convergent Channels 5.3 Magneto-hydrodynamic Couette Nanofluid Flow 5.4 Nanofluid Between Parallel Plates 5.5 Vibrational of Nanobeams 5.6 Buckling Analysis of a Single-Walled Carbon Nanotube
