Abstract
Nature of carbon nanotubes (CNT’s) mechanical characteristics can only be disclosed through advanced studies. Carbon nanotubes show diverse features in radial and axial directions when studied geometrically. Since CNT’s have two dimensional symmetrical behavior and they are in cylindrical shape, they show strong electrical and thermal conductivity in base fluid. In order to develop energy equation, such characteristics must be kept in view, we nominate the heat flux model of Catteneo-Christov. Carbon nanotubes of singlewall and multiwall are analyzed and compared in base fluid of water. Cylindrical coordinates are used in mathematical formulation and modeling for the flow equations to be converted to partial differential equations. For solution and study of fluid equations shooting method and Keller box scheme are used. Our computations resulted in an increase in fluid temperature due to thermal relaxation time, while fluid temperature decreases with an increases in Prandtl number. Further more, porosity also has fluid velocity as its decreasing function. The results are displayed through tables and graphs.
