On the Radiative Heat Transfer in a Viscoelastic Boundary Layer Flow Over a Stretching Sheet

Abstract

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.
