Answer:
Explanation:
The influence of magnetic field, thermophoresis, and the first-order reaction of a dissipative micropolar flow involving two coaxial inner rotating horizontal cylinders are studied both analytically and numerically. The motion of the fluid is generated due to the rotation of the inside cylinder with a constant angular velocity. The internal and external cylinders are kept maintained at different uniform temperatures and concentrations. The transformed systems of differential equations are solved systematically using modified Bessel functions and numerically with the fourth-order Runge–Kutta scheme along with a shooting method. The temperature and concentration are examined for a variety of parameters which govern the flow through graphical illustrations. The results obtained are in very good agreement with benchmark solutions for a particular case.
