Copper and gold nanoparticles have been shown to improve the lubrication properties of engine oil. The nanoparticles can fill in the gaps and scratches on the surface of the engine parts, reducing friction and wear, copper nanoparticles have high thermal conductivity, which can improve the heat transfer properties of engine oil. This is helpful for the reduction and control temperature of the engine, which may improve longevity and efficiency. Due to the above applications, this work contains copper and gold nanoparticles suspended in engine oil. In this work, we analyze entropy generation, thermal stratification, heat generation, and Cattaneo–Christov heat and mass flux of Jeffery hybrid nanofluid. The fluid flow is taken through the stretched cylinder. The governing equations in nonlinear PDEs are converted to nonlinear ODEs by using the transformations. Cylindrical coordinates are used for mathematical formulation. The homotopy analysis method is used to obtain the analytical solution of the problem. Velocity, temperature, and concentration profile have different parameters involved. The results show that the velocity of the fluid is enhanced with the curvature parameter and stagnation variable. The temperature profile decreased with the thermal stratification parameter. The concentration profile shows decreasing behavior with an increase in chemical reaction parameter and solutal time relaxation parameter. Entropy generation is enhanced with heat generation parameters. The results obtained in this work are helpful for the betterment of lubricants used in automotive, industrial oil, greases, and metal working fluids.
