摘要

在本研究中，不同纳米流体(AL2O3, CuO, SiO2, ZnO)的流场和换热，在通道内紊流强制对流。通道表面热Th= 310 K。在恒定水普朗特数为6.99，雷诺数为2万、3万、4万、5万~ 6万，纳米颗粒体积分数为0、0.01、0.02、0.03、0.04，纳米颗粒直径为30 nm的条件下进行了模拟。利用有限体积法、SIMPLE算法和k-e算法对控制方程进行了数值求解。数值结果表明，随着雷诺数和体积分数的增大，平均努塞尔数增大。

Numerical study of convective heat transfer and of turbulent forced of differents Nanofluids in channel

In this study, the flow field and heat transfer of differents nanofluids (AL2O3, CuO, SiO2, ZnO), turbulent forced convection in a channel. The surface of the channel is hot Th= 310 K. Simulations are carried out for constant water Prandtl number of 6.99, Reynolds numbers from 20,000, 30,000, 40,000, 50,000 to 60,000, nanoparticles volume fractions of 0, 0.01, 0.02, 0.03, 0.04 and nanoparticles diameter of 30 nm. The finite volume method and SIMPLE algorithm and k-e are utilized to solve the governing equations numerically. The numerical results showed that with enhancing Reynolds numbers and volume fractions, average Nusselt number increases.
