In this work, we establish a model to describe the unsteady magnetohydrodynamic (MHD) flow of fractional Oldroyd-B fluid between parallel plates on heat transfer, by introducing the fractional derivative into the constitutive equation. The flow is driven by magnetic, electroosmotic and pressure gradient forcings. In the numerical implementation, the spectral collocation method combined with fast algorithm based on sum-of-exponentials (SOE) approximation is performed to solve the model. Effects of several parameters on the velocity profiles, temperature field and Nusselt number are investigated graphically.

快速评估平行板之间部分 Oldroyd-B 流体的磁流体动力流动和热传递

在这项工作中，我们通过在本构方程中引入分数阶导数，建立了一个模型来描述传热平行板之间分数阶 Oldroyd-B 流体的非定常磁流体动力学 (MHD) 流动。流动是由磁力、电渗力和压力梯度力驱动的。在数值实现中，采用光谱搭配法结合基于指数和(SOE)近似的快速算法对模型进行求解。以图形方式研究了几个参数对速度剖面、温度场和努塞尔数的影响。
