In this research, heat transfer along with entropy of an unsteady non-Newtonian Casson nanofluid flow is studied. The fluid is positioned over a stretched flat surface moving non-uniformly. The nanofluid is analyzed for its flow and heat transport properties by subjecting it to a slippery surface, which is convectively heated. The governing mathematical equations describing the physical characteristics of Casson nanofluid flow as well as heat transfer models are abridged under boundary layer flow assumptions and Roseland approximations. Governing equations of flow problem are formulated in partial differential equations. A computative technique, Keller box accustomed to find the self-similar solution of equations that converted into ordinary differential equations (ODEs) by using proper transformations. Two different classes of nanofluids, copper-methanol (Cu–MeOH) and titanium-methanol (TiO2–MeOH) are considered for our analysis. Significant results of various parameters in flow, heat, skin friction, Nusselt number and entropy analysis are elaborate graphically. The remarkable finding of this work is that the Cu–MeOH nanofluid is better transfer source as compared to TiO2–MeOH nanofluid.

由于受到颗粒形状因子影响的非线性拉伸片对 Casson 纳米流体的计算检查:Tiwari 和 Das 模型

在这项研究中,研究了非定常非牛顿 Casson 纳米流体流的热传递和熵。流体定位在非均匀移动的拉伸平面上。通过将纳米流体置于对流加热的光滑表面,分析纳米流体的流动和热传输特性。描述 Casson 纳米流体流动的物理特性以及传热模型的控制数学方程在边界层流动假设和 Roseland 近似下被删减。流动问题的控制方程用偏微分方程表示。作为一种计算技术,Keller box 习惯于通过使用适当的变换来找到转换为常微分方程 (ODE) 的方程的自相似解。两种不同类别的纳米流体,2 –MeOH) 被考虑用于我们的分析。流量、热、皮肤摩擦、努塞尔数和熵分析中的各种参数的显着结果以图形方式详细说明。这项工作的显着发现是,与 TiO 2 -MeOH 纳米流体相比,Cu-MeOH 纳米流体是更好的转移源。
