Abstract

During the design of thermal management systems involving PCMs, analysis tools are essential for determining the amount of PCM required, optimal instalment locations, and the heating-cooling transient behavior of the systems. Computational Fluid Dynamics (CFD) solvers are often employed for these tasks, as they can account for both conduction and advection effects during PCM phase transitions. However, CFD simulations can be computationally expensive, particularly when solving transient behaviour. An alternative approach for PCM simulations is the Finite Element Method (FEM), which offers computationally inexpensive heat transfer analyses while providing good accuracy for thermal energy storage design, including phase transitions. This study has focused on thermal analysis of paraffin wax performed by FEM.

Özet

Faz değiştiren malzemelerin (FDM'ler) kullanıldığı termal sistemlerinin tasarımı sırasında, analiz araçlarının kullanımı önem arz eder. Nümerik analizler, FDM miktarının belirlenmesi, optimal montaj konumları ve sistemlerin ısınma-soğuma sürelerinin belirlenmesi için esastır. Bu amaç doğrultusunda genellikle Hesaplamalı Akışkanlar Dinamiği (HAD) çözücüleri kullanılır. Ancak, HAD simülasyonları, özellikle zamana bağlı çözümlerde oldukça hesaplama maliyeti getirir. FDM simülasyonları için bir alternatif yaklaşım olarak Sonlu Elemanlar Yöntemi (SEY) tercih edilebilir. Bu çalışma, FEM tarafından gerçekleştirilen parafin mumunun termal analizine odaklanmıştır.
