This study explores the thermal enhancement of rotating magnetohydrodynamic water-based nanofluids containing single-wall ( \(SWCNTs\) ), multi-wall carbon nanotubes ( \(MWCNTs\) ), and a (SWCNTs-MWCNTs) hybrid nanofluid over a stretching sheet. The main aim of this article is to enhance the efficiency of the thermal transport due to the carbon nanotubes thermal conductivity. The governing three-dimensional PDEs for momentum, energy, mass transfer, and microorganism are transformed into set of nonlinear ODEs by utilizing similarity functions. The resulting nonlinear ODEs are solved numerically using bvp4c package based on fourth-order Runge–Kutta (RK4) method with MATLAB platform. The graphical and tabulating outcomes of various physical parameters are used to reveal the sensitivity of the flow, heat and mass transfer properties, and comparison of current work. Through our results, the increment of magnetic parameter \(M\) , porosity parameter \(K\) , and rotation parameter \(\lambda \) declines the velocity of the base fluid along the \(x\) -direction, while the opposite behavior is observed along the \(y\) -direction. Additionally, the velocities along \(x\) , \(y\) -direction, temperature profile, and motile microorganism distributions of nanofluids are found to be lower than those of hybrid nanofluids, while the volumetric solutal distribution is found to be higher.
