Abstract Thermally developing laminar flows in ducts with temperature-dependent viscosity variation are analyzed, where the Arrhenius model for the variation of the viscosity with the temperature is made. The Darcy flow model is assumed. The case of isothermal boundaries is treated. It is observed that the developing velocity and temperature profiles differ from those of constant property case. It is also concluded that the fully developed region will be reached later than the constant property case. However, no significant change has been observed in the value of the fully developed Nusselt number since the fully developed velocity distribution is the same as the constant property case and so is the temperature profile.
