In current study, heat transfer and viscous dissipation effects in nanoliquid flow through a porous stretchable cylinder are examined. The upgraded heat transport rate in the base fluid with tiny-sized nanoparticles is investigated. Convective heating and non-linearly thermal radiation effects are investigated. In this analysis, solid particles MoS2 & Ag and base fluid engine-oil are used. Moreover, boundary layer approximations are used to model a set of PDEs. The structure model of PDEs is reduced into non-dimensional set of ODEs with the help of recommended similarity transformations. The converted equations jointly with specific boundary restrictions are solved numerically by using the bvp4c solver (shooting scheme) in computational software MATLAB. The behavior of prominent parameters against flow and thermal fields are analyzed. From the results, we observed that velocity enhances for larger solid volume fraction. Furthermore, temperature of fluid is increased via greater estimations of thermal Biot number. The nanofluid has improved heat transport rate and therefore the current analysis has many applications in nano-sized devices of cylindrical shapes.
