The paper presents a numerical investigation using ANSYS Fluent v2021 to study a metal foam heat exchanger integrated into the absorber plate of a double tube heat exchanger for a solar flat plate collector. The goal is to analyze the system’s thermal and fluid flow behavior. Water is employed as the working fluid in the simulations. Three types of metal foam (Nickel, Copper, and Aluminum) with porosities ranging from 0.80 to 0.90 and pore densities of 10 to 30 are considered. The simulations are validated against experimental data obtained under similar operating conditions. In the experiments, a nickel metal foam with a porosity of 0.90 and a pore density of 10 PPI is inserted into the double tube heat exchanger's annular space. Temperature and pressure drop measurements are taken with and without the metal foam. The numerical simulations adopt the Reynolds-Averaged Navier-Stokes (RANS) equations with the k-epsilon turbulence model to simulate fluid flow and heat transfer. The metal foam heat exchanger is modeled as a porous medium. The investigation aims to identify the optimal metal foam configuration for enhanced thermal performance in solar thermal applications, providing insights for engineering design and optimization. The performance evaluation criteria enable a comprehensive understanding of the effectiveness and applicability of the metal foam heat exchanger for solar thermal applications, providing valuable insights for engineering design and optimization.
本文利用ANSYS Fluent v2021软件对太阳能平板集热器双管换热器吸收板集成金属泡沫换热器进行了数值研究。目标是分析系统的热和流体流动行为。模拟中采用水作为工作流体。三种类型的金属泡沫(镍，铜和铝)，孔隙率范围为0.80至0.90，孔隙密度为10至30。仿真结果与相似工况下的实验数据进行了对比验证。在实验中，将孔隙率为0.90、孔密度为10ppi的金属镍泡沫插入双管换热器的环形空间。温度和压降测量采用和不采用金属泡沫。数值模拟采用reynolds - average Navier-Stokes (RANS)方程和k-epsilon湍流模型来模拟流体的流动和传热。将金属泡沫换热器建模为多孔介质。该研究旨在确定在太阳能热应用中增强热性能的最佳金属泡沫结构，为工程设计和优化提供见解。性能评价标准能够全面了解金属泡沫换热器在太阳能热应用中的有效性和适用性，为工程设计和优化提供有价值的见解。
