This paper addresses MHD Sutterby fluid flow by a rotating disk of variable thickness. Thermal radiation is nonlinear. Impact of homogeneous–heterogeneous reactions is also examined. For the development of convergent solution the homotopy concept is utilized. Skin friction coefficient, temperature, velocity and Nusselt number are addressed. Radial, azimuthal and tangential velocities are enhanced by increasing the disk thickness. For larger disk thickness coefficient there is decay in skin friction. Nusselt number is enhanced for larger Prandtl number and radiation parameter. •MHD Sutterby fluid flow by a rotating disk of variable thickness is considered.•Thermal radiation is nonlinear.•Impact of homogeneous–heterogeneous reactions is also examined.•Tangential and radial velocities decay for larger (M) while both have increasing behavior for (n).•Fluid temperature decreases for Pr while reverse is seen for (R) and (θw).
