Abstract

In this work, CNTs are incorporated into two distinct types of base fluids, namely Hexanol and Paraffin oil, to formulate advanced nanofluids. The stretching of the co-axial cylinder causes nanofluid flow. These assumptions are modelled in the form of PDEs and are transformed into ODEs by employing proper transformations. Resultant ODEs are treated by employing the bvp4c technique. Computational results are displayed via graphs and tables. A comparative analysis of nano-composites is made. The heat source is accounted for in a comprehensive thermal field analysis. The obtained outcomes reflect that the velocities of the nanofluid obtained from the dispersion of MWCNTs in base fluids are dominant over the nanofluids generated from SWCNTs and base fluids. Furthermore, the temperature of the obtained nanofluids from SWCNTs and base fluids is higher than that of the generated nanofluids from MWCNTs and base fluids. Also thermal field rises for a large heat source parameter and is more dominant in the case of hexanol oil and SWCNTs base-generated nanofluids.
