In this study, rotational nano liquid movement above a linearly stretching surface has been formulated. A two-phase model is used for this analysis. Base fluid engine oil and two distinct types of nanoparticles are used as nanoparticles, i.e. copper and aluminum oxide (Cu &Al2O3). This study is aimed to describe the changed possessions on velocity and temperature for rotational nanofluid flow above a linear enlarging surface in the existence of the slip effect. The leading structure of PDEs is converted into ODEs with a similarity transformation. Numerical findings are gained utilizing a sophisticated numerical approach. For both nanofluids, the results for rotational flow and heat transmission characteristics are emphasized with the help of graphs. At the linear extending surface, the influence of physical concentrations like heat flow rates and skin friction coefficients is investigated and visually clarified. Cunanoparticles proved to be better heat carriers than Al2O3 nanoparticles.
