摘      要：The theoretical analysis of the mixed convective Buongiorno nanofluid flow in an inclined annular microchannel with convectively heated walls subjected to the effects of nonlinear thermal radiation,exponential heat source(EHS),thermal dependent heat source(THS)is carried *** description of the Buongiorno nanofluid is implemented to analyze the Brownian diffusion and thermo-migration *** general boundary conditions for the velocity,thermal,and nanoparticle volume fraction(NVF)are *** solutions for fully developed governing equations are obtained using bvp5c solver and verified with *** optimization of heat transport rates is made by using the Box-Behnken designbased response surface *** is found that the Lorentz force and the inclination angle of the annulus significantly affect the rheological characteristics of the *** increase thermal energy in the system through Brownian diffusion and thermophoresis,resulting in increased temperature *** heat sources would serve as an important tool for modulating the thermal field in microchannel,as they are directly *** low-level values of the thermal Biot number,the exponential heat source,and the thermal radiation parameter,it is possible to attain the maximum Nusselt number on both walls of the annulus.
