Numerical simulation and modeling of entropy generation in Marangoni convective flow of nanofluid with activation energy

In this article, Marangoni convective flow of nanofluid is considered. Entropy generation minimization is also considered. Equations are constructed for Buongiorno model of nanofluid. Flow is generated by rotating disk. Activation energy, nonlinear mixed convection, and MHD effects are also taken in consideration. Ordinary differential equation is formed by using appropriate variables. Results are formed by using Shooting method. Results of temperature, axial velocity, entropy, radial velocity, concentration, and Bejan number are discussed through graphs. Radial and axial velocities are increasing functions of Marangoni ratio parameter. Temperature and concentration are decreasing functions of Marangoni ratio parameter. Entropy is increasing function of Marangoni ratio parameter. Bejan number declines via Marangoni ratio parameter.
