摘要
This article presents a numerical investigation on the convective heat transfer performance of nanofluids over a permeable stretching surface in the presence of partial slip, thermal buoyancy and temperature dependent internal heat generation or absorption. Two different types of nanoparticles, namely Cu and Al2O3 are considered by using water-based fluid with Prandtl number P-r = 6.785 for simulating the heat transfer and flow behavior of nanofluids. The proposed model is validated with the available experimental data and correlations. The similarity solutions which depend on nanoparticle volume fraction phi (0 <= phi <= 0.2), slip parameter, suction/injection parameter, etc. are presented through graphs and tables and discussed in detail.
