Abstract:
This paper explores the themtal radiation effect in the two- dimensional and magnetohydrodynamic (Ml-ID) flow of an Nanofluid in a stretching convergent/divergent channel. Collocation method (CM) is employed to solve resulting eqttation. The results are compared with Numerical solution in order to verify the accuracy of the proposed methods in various values of key parameters. Comparison between CM and numerical method shows that CM is an exact and high efficient method for solving these kinds of problems The results show that the fluid velocity and temperature profile increase with the increasing of stretching parameter. The results also reveal that the temperature profile increases withthe increasing of the hartman number and it decreases with the rising of radiation parameter. Finally, effect of at various angles between the plates. the Reynolds number, the magnetic field, the thennal radiation and nanoparticle volume fraction as parameters on velocity and temperature distribution are depicted and discussed in the proposed work.
