Abstract This investigation examines the characteristics of nonlinear mixed convection flow by stretching sheet with variable thickness. Double diffusion Cattaneo-Christov heat flux model is implemented. Temperature dependent thermal conductivity is employed. Flow of Maxwell fluid is formulated. Suitable transformations yield nonlinear ordinary differential equations. Convergence of series solutions for the velocity, temperature and concentration is discussed. Characteristics of velocity, temperature and concentration distributions for different involved parameters are examined. Nusselt number is calculated and discussed. Clearly an enhancement in Deborah number causes a reduction in velocity profile. There is a decline in temperature profile by increasing the thermal relaxation parameter. Concentration distribution decays with respect to concentration relaxation parameter.
