The aim of current research is to analyze the thermal radiation on nanofluid flow between two circular cylinders under influence of magnetic field using two effectual computational methods. The applied numerical and analytical techniques are differential quadrature scheme and optimal homotopy asymptotic approach, respectively. As a preeminent finding from this investigation, it can be deduced that the accuracy, reliability and simplicity of these methods are excellent. Further, the influences of various physical variables such as aspect ratio, Reynolds, Hartmann and Eckert numbers are examined in details. The outputs demonstrate that the temperature profile increases with Reynolds and Eckert numbers elevation, however it decreases by increasing Hartmann number and radiation criterion. Also, Nusselt number enhances by increasing radiation criterion and Hartmann number.
