Abstract

Here thermo-diffusion and diffusion-thermo behaviors in mixed convection radiative flow by a rotating cone is examined. Viscous dissipation and radiation in energy equation are present. Dufour and Soret effects are discussed. Entropy optimization is considered. Nonlinear PDEs are reduced to ODEs through appropriate variables. Nonlinear expressions are solved by ND-solve technique. Characteristics of different involved variables of concentration, entropy optimization, Bejan number, temperature and velocity are deliberated. Computational results of gradient of velocity, Nusselt number and mass transfer rate are scrutinized via tables. Comparative study of current and previous published results in literature is also made. A good agreement is noticed. Tangential and azimuthal velocity components are decreased for higher slip parameter. Azimuthal and tangential velocities have reverse effects against mixed convection parameters. Temperature has contrasting effect for larger radiation parameter and Prandtl number. Entropy optimization have similar behavior versus radiation parameter.
