RÉSUMÉ

The influence of thermal radiation on MHD boundary layer flow of a tangent hyperbolic nanofluid with zero normal flux of nanoparticles over an inclined exponentially stretching sheet in the presence of suction/blowing is studied. The partial differential systems are transformed to ordinary differential systems by using appropriate similarity transformations. The transformed systems are solved numerically by the Runge-Kutta fourth-order method with shooting technique. The velocity, temperature, and nanoparticle volume fraction profiles are discussed for different physical parameters. As the skin friction and Nusselt number are exhibited and analyzed as well. It is found that the thermal radiation enhances the effective thermal diffusivity and the temperature rises. It is also observed that the buoyancy parameter strengthens the velocity field, showing a decreasing behavior of temperature and nanoparticle volume fraction profiles.
