摘要
Here impact of activation energy in binary chemically reactive flow of third grade fluid is addressed. Flow is discussed by a stretchable rotating disk. Novel characteristics regarding thermophoresis and Brownian movement have been analyzed. Nonlinear thermal radiation is considered. Convergent series solutions to nonlinear problems are computed. Impacts of various physical parameters like Brownian motion parameter, Prandtl number, mixed convection parameter, thermophoresis parameter, radiation parameter, activation energy, chemical reaction and Schmidt number on the velocity, concentration and thermal fields are discussed and analyzed. Velocity, temperature and concentration gradients are computed and discussed through various flow variables. Their obtained results present that velocity, temperature, concentration fields are strongly depends on the flow parameters. Main conclusions are presented.
