Abstract

Background:

In many energy systems, performance enhancement of PCM-mounted systems with various fin designs and channel arrangements becomes crucial. In this study, effects of using zigzag shaped fins on melting of encapsulated PCM installed in a mixing chamber under forced convection for different inlet-outlet port cases and in various flow configurations are analyzed.

Methods:

Using the finite element method, the effects of the following on the flow field, temperature field, and melt fraction are examined: The mixing streams’ flow rate ratio, fin size, fin number, wavy fin non-dimensional amplitude, and wavy fin wave number. The estimation of melt fraction dynamics is done using a modeling approach based on ANFIS.

Significant Findings:

In comparison to the lowest FRR configuration, melting time decreases by 38.8% and 43.4% in the flat and zigzag fin scenarios with the highest FRR. When comparing the maximum and lowest fin lengths with

N_{f} = 4

, the melting time for the flat and zigzag fins drops by 19.6% and 14.6%, respectively. The amount of melt fraction is increased by aligning the intake ports orthogonally. Considering the opposing inlets and outputs of the mixing chamber, the worst configuration for melt dynamics is achieved. Using a modeling approach based on ANFIS, melt fraction dynamics is successfully estimated.

锯齿形翅片对PCM混合通道熔化过程的影响及基于ANFIS的性能估计

背景：在许多能源系统中，采用各种翅片设计和通道布置的pcm安装系统的性能增强变得至关重要。本文分析了在强制对流条件下，在不同进出口工况和不同流动形态下，使用锯齿形翅片对安装在混合室内的封装PCM熔化的影响。方法：采用有限元方法，考察了混合流的流量比、翅片尺寸、翅片数、波浪鳍无量纲幅值和波浪鳍波数对流场、温度场和熔体分数的影响。采用基于ANFIS的建模方法对熔体分数动力学进行了估计。显著发现：与最低FRR配置相比，最高FRR的平鳍和之字形翼的融化时间分别缩短了38.8%和43.4%。当最大和最小翅片长度为Nf=4时，扁平和之字形翅片的融化时间分别缩短了19.6%和14.6%。通过垂直对齐进气口来增加熔体分数的数量。考虑到混合室的进口和出口相反，得到了熔体动力学的最差配置。利用基于ANFIS的建模方法，成功地估计了熔体分数动力学。
