Abstract

The present study aims to implement energy, exergy, and economic (3E) analysis to investigate the enhanced performance of wavy plate heat exchangers (PHEs) using water-Al₂O₃ as nanofluid. The systematic impacts of five main geometrical and operational independent parameters of PHEs–namely hot-side inlet temperature (323–363 K), mass flow rate (1.00–2.00 kg/s), fin wavelength (2.5–100 mm), internal plate material thermal conductivity (16.3–401 W/(m.K)), and volume concentration of nanoparticles (0–4 %)–on their functional output parameters were investigated using Ansys-Fluent software. These parameters include velocity and temperature variation, Nusselt number, number of transfer units, thermal efficiency, effectiveness, pressure drop, Colburn factor, exergy destruction, area goodness factor (AGF), volume goodness factor (VGF), and economic factors. The statistical method of Taguchi was used for the design of experiment (DOE), and the EES software was used to perform the exergo-economic analysis. Results show, mass flow rate, internal plate wavelength, and inlet temperature are the most significant impactful parameters. Based on the results, the Nusselt number and thermal efficiency of PHEs can be improved by 233 % and 200 %, respectively, with a penalty of 61 % in the capital cost (purchasing components) of PHEs. The exergy destruction in the 25 studied cases ranged from 1.483 kW to 36.18 kW. It was noted that the wavy plates combined with modest nanoparticle concentration (1–2 % by volume) and moderate corrugation wavelength provide the best thermo-economic result.

纳米流体波板换热器设计中的能量、能源和经济性能分析

本研究旨在实施能源、能源和经济（3E）分析，以研究使用水- al2o3作为纳米流体对波浪板式换热器（PHEs）性能的增强。研究了热侧进口温度（323-363 K）、质量流量（1.00-2.00 kg/s）、翅片波长（2.5-100 mm）、内板材料导热系数（16.3-401 W/(m)）等5个主要几何和运行参数对phs的系统影响。K))，以及纳米颗粒体积浓度（0 - 4%）对其功能输出参数的影响，使用Ansys-Fluent软件进行研究。这些参数包括速度和温度变化、努塞尔数、传递单元数、热效率、有效性、压降、科尔本系数、火用破坏、面积优良系数（AGF）、体积优良系数（VGF）和经济因素。试验设计采用田口统计学方法（DOE），采用EES软件进行试验经济分析。结果表明，质量流量、内板波长和进口温度是影响最显著的参数。结果表明，该方法可使精电炉的努塞尔数和热效率分别提高233%和200%，而精电炉的资本成本（购买部件）则降低61%。在25个研究案例中，火用破坏的范围从1.483 kW到36.18 kW。结果表明，适当的纳米颗粒浓度（体积比为1 - 2%）和适当的波纹波长相结合的波纹板具有最佳的热经济效果。
