Rotating dynamical system (centrifugal and coriolis forces) is employed in this analysis to study the influence of enthalpy and rotated fluid flow in a finite three dimensional channel. The exponential varying viscosity model is used in this paper. The chemically reactive diffusion is examined with Arrhenius activation energy. The thermal conductivity and diffusivity are assumed to be linear dependent. The lower surface has velocity in negative direction but upper surface is fixed. The main equations in the three-dimensional form are converted into non-dimensional form via applicable scaling transformations. The shooting process is applied and coded in Matlab software to get the numerical solution of the non-linear ordinary differential problem. The varying shapes of velocities, fluid temperature and concentration functions are calculated to disclose the physical nature of this analysis.
