The current article analyzes the study on “MHD - mixed convective boundary layer flow” SiO2 -water, SiO2 -Ethylene glycol & SiO2 -Engine oil nano fluids “above a vertical circular-cylinder” under the influence of radiant heat and magnetic-field Passing through a porous medium. Similarity variable(s) are used to transform the main PDE (partial differential equations) into the ODE (ordinary differential equations). The governing equations are then solved by the method of R- K –Fehlberg with shooting technique numerically. MATLAB is used for the presentation of results. The impact of pertinent- parameters on factors like velocity and temperatures of assisting flow, convective flow and opposing flow are unyielding and detailed info are presented through various plots. The “coefficient of skin friction (C_f)” and “local Nusselt number (Nu)” for different parameter(s) are computed for the three flows and tabulated.
