在本研究中，考虑热辐射，研究了两个平行板之间非稳态纳米流体流动的传热传质特性。考虑两相模型以模拟纳米流体。基本偏微分方程被简化为常微分方程，并使用四阶龙格-库塔法进行数值求解。考虑了挤压数、辐射参数、施密特数、布朗运动参数、热泳参数和埃克特数对流动、传热、传质的影响。结果表明，浓度边界层厚度随着辐射参数的增加而增加。还可以发现，努塞尔数与埃克特数、施密特数、挤压参数和辐射参数有直接关系。
In this study, heat and mass transfer characteristic of unsteady nanofluid flow between two parallel plates is investigated considering thermal radiation. Two phase model is considered in order to simulate nanofluid. The basic partial differential equations are reduced to ordinary differential equations which are solved numerically using the fourth-order Runge-Kutta method. The effects of the squeeze number, radiation parameter, Schmidt number, Brownian motion parameter, thermophoretic parameter and Eckert number on flow, heat and mass transfer are considered. Results indicate that concentration boundary-layer thickness increases with increase of Radiation parameter. Also it can be found that Nusselt number has direct relationship with Eckert number, Schmidt number, squeeze parameter and Radiation parameter.
