Thermal conductivity plays pivotal role in accelerating the heat transfer rate in nanofluids (NFs), besides other parameters such as nanoparticle volume fraction, shape and size of nanoparticle and combination of nano materials-base fluid. This article numerically simulates the heat transport phenomena in carbon nanotubes in boundary layer flow induced by a moving surface in linear velocity. The role of two different thermal conductivity models, namely, Xue and Hamilton-Crosser are discussed in comparative manner. Governing equations are solved using similarity solution approach and shooting method. Important physical parameters such as Nusselt number and skin friction are computed at surface for both the models and thermal characteristics are analysed in both these models. SWCNT dominates MWCNT in terms of heat exchange rate. Skin friction increases with Forchheimer term.
