Rheology of Maxwell material on dynamics of gyrotatic microorganism with variable characteristics and hydrodynamic impacts

The cooling systems in thermal devices are remarkable in modern technology, and they have been achieved by active and passive heat transfer enhancement techniques. To improve heat movement in thermal systems, scientists and engineers have developed several methods. The increasing effect for improving heat transfer that has been continually researched is the nanofluids, Joule heating, magnetic field, and surface heating agents. This research aims to investigate the thermal and solutal characteristics of the magnetized stagnation point flow of Maxwell material induced by shrinking surface containing microorganisms. The analysis focuses on the effects of nonlinear thermal radiation, irregular heat generation/absorption, and Ohmic heating on the thermal energy transfer in fluid. Furthermore, the mass transfer phenomenon is also investigated with the impact of activation energy and mass diffusivity. The governing flow equations of Maxwell fluid are formed in the form of partial differential equations which are turned into ordinary differential equations by applying similarity transformation. The built-in MATLAB software bvp4c is used to solve ODEs, and the results are presented graphically with detailed discussion. As a primary result, higher values of suction and shrinking parameters boost the flow field. Further, an increase in the Eckert number, material parameter, and radiation rate considerably improves the temperature distribution. Additionally, the solutal distribution enhances against the variation of activation energy and reaction rate.
