Abstract

Abstract Mono, hybrid, and ternary nanofluids were tested inside the plain and twisted-tape pipes using k-omega shear stress transport turbulence models. The Reynolds number was 5,000 ≤ Re ≤ 15,000, and thermophysical properties were calculated under the condition of 303 K. Single nanofluids (Al2O3/distilled water [DW], SiO2/DW, and ZnO/DW), hybrid nanofluids (SiO2 + Al2O3/DW, SiO2 + ZnO/DW, and ZnO + Al2O3/DW) in the mixture ratio of 80:20, and ternary nanofluids (SiO2 + Al2O3 + ZnO/DW) in the mixture ratio of 60:20:20 were estimated in different volumetric concentrations (1, 2, 3, and 4%). The twisted pipe had a higher outlet temperature than the plain pipe, while SiO2/DW had a lower T out value with 310.933 K (plain pipe) and 313.842 K (twisted pipe) at Re = 9,000. The thermal system gained better energy using ZnO/DW with 6178.060 W (plain pipe) and 8426.474 W (twisted pipe). Furthermore, using SiO2/DW at Re = 9,000, heat transfer improved by 18.017% (plain pipe) and 21.007% (twisted pipe). At Re = 900, the pressure in plain and twisted pipes employing SiO2/DW reduced by 167.114 and 166.994%, respectively. In general, the thermohydraulic performance of DW and nanofluids was superior to one. Meanwhile, with Re = 15,000, DW had a higher value of η Thermohydraulic = 1.678.

基于三元混合纳米流体的扭曲湍流插片热系统热水力性能研究

摘要使用k-omega剪切应力传输湍流模型在平带管和扭曲带管内测试了单体、混合体和三元纳米流体。雷诺数为5000≤Re≤15000，在303的条件下计算了热物性 K.在不同的体积浓度（1、2、3和4%）下，估计了混合比为80:20的单一纳米流体（Al2O3/蒸馏水[DW]、SiO2/DW和ZnO/DW）、混合比为60:20:20的混合纳米流体（SiO2+Al2O3+ZnO/DW）和三元纳米流体（Si2+Al2O3+ZnO/DW）。扭曲管的出口温度高于普通管，而SiO2/DW的T out值较低，为310.933 K（平管）和313.842 Re=9000时的K（扭曲管）。热系统使用6178.060的ZnO/DW获得了更好的能量 W（平管）和8426.474 W（扭曲管）。此外，在Re=9000时使用SiO2/DW，传热改善了18.017%（平管）和21.007%（扭曲管）。在Re=900时，采用SiO2/DW的平管和扭曲管中的压力分别降低了167.114%和166.994%。总的来说，DW和纳米流体的热工水力学性能优于DW。同时，当Re=15000时，DW的ηThermohydraulic=1.678值更高。
