As knowledge in flow and heat transfer is showcased in macro/micro-channel areas, consistent advancement is essential to familiar with fundamental phenomena associated. The free convection study encompasses the temperature-dependent viscosity and uniform magnetic field effect. The dimensionless equations governing the flow are modeled and solved semi-analytically via Akbari-Ganji’s Method (AGM). The velocity, energy, concentration and physical characteristics of the flow results are obtained and discussed with the aid of tables and graphs. It is found that a higher value of the slip parameter diminishes the velocity distribution at the annular gap and surfaces, while, the temperature-dependent exponential variability model enhances the fluid velocity.http://mcs.qut.ac.ir/article_254909_f63f07015c9060f393df332681689be5.pdf
