将非牛顿流体力学理论及其方法推广应用于建立纳米流体-新概念非牛顿流体扰动本构方程,并研究其传热流动。韩式方发展了有特色的非牛顿流体扰动本构理论,并成功地应用于研究非牛顿流动稳定性,可以应用于非牛顿流动研究。将非牛顿流体扰动本构理论推广至建立新的纳米流体微扰动模型,对单相流体模型进行微扰动修正。纳米流体强化热交换机制：悬浮粒子增加二相混合体的热传导率;极细粒子随机运动,热耗散加速流体中能量转换过程。在新的纳米流体扰动本构方程基础上。研究了纳米流体传热流动,其结果表明,Nusselt数随纳米粒子的体积分数的增加而增加,其趋势与实验结果一致,表明本理论方法是合理的,可以推广于应用一系列纳米流体流动问题。

英文摘要：

The non-Newtonian fluid flow theory is applied to study nanofluid motion which is considered as a new concept non-Newtonian fluid. Due to gliding motion of nano particles with respect to basic flow and thermal diffusion disturbed flow caused by random motion of nano-particles,the new concept non-Newtonian fluid is considered as a nearly basic flow,which is generalized by a slightly rotation of basic flow of one phase fluid with respect to the 1,2,3 axes of the Cartesian coordinate system. As an important application of the developed disturbed constitutive theory,the two dimensional thermal flow of nanofluid between two infinite planes is studied.The flow between two infinite planes is treaded as a flow with dominating extension. The developed disturbed constitutive theory can be used for the thermal nanofluid flow.
