Many researchers have studied the radiative heat transfer in a viscoelastic boundary layer flow over a stretching sheet after simplifying the complex nature of the radiative heat flux by expanding the fourth power of temperature $(T4)$ in Taylor series about free-stream temperature $(T∞)$ and neglecting the higher-order terms. Similarity solutions obtained by them are found to be valid only in the asymptotic region. This article suggests a modification in the linearization of $T4$ by introducing wall temperature $(Tw)$ as well as freestream temperature $(T∞)$ to capture the realistic nature of the temperature distribution in the boundary layer flows from locally nonsimilar solutions.
