This work lineup a theoretical analysis on the Marangoni convective flow and exchange of heat rate in carbon nanotubes (CNTs)-based nanofluid towards a porous surface, which has useful applications in science and engineering departments. The famous two types of CNTs, are accounted as solid nanoparticles while kerosene oil is exercised as a base liquid for the dispersion of nanoparticles. The impact of suction/injection and thermal radiation is involved in the model. The system of highly nonlinear ordinary differential equations (ODEs) is derived by reasonably suitable transformations. The homotopy analysis procedure is used to compute the exact solution for a reduced system of equations. For validation of results, the numerical solution is also developed with the help of bvp4c solver in MATLAB. Characteristics of dimensionless velocity and temperature fields are reported in the light of prominent parameters, such as the suction/injection parameters, porosity factor, nanoparticles solid volume fraction, radiation parameter, constant exponent, and Brinkmann number, respectively. The impact of the respective sundry parameters on flow field is discussed after each graph, comprehensively. The performance of the heat transfer rate by Nusselt number on the surface is reported in tabular form at the end of the text. The outcomes exhibit that the velocity and temperature profiles are declined for increasing values of the porosity factor.
