“…The very important effects of hybrid nanofluxes and PCMs on energy storage and energy efficiency have begun to be revealed by studies. Li et al (1996), Ali Rabienataj Darzi et al (2013), Kousksou et al (2014), Hosseini and Rahimi (2019), Xu and Wang (2019), Doshi et al (2022), Kolsi (2022), Ibrahim and Koca (2023a, 2023b) and Manjunath et al (2021) made a detailed study on the convection HT, and flow structure property of the jet was investigated by vertically striking a hemispherical plate. Bounded slit jet impinging on the isothermal hot flat surface of the minichannel with nanofluid was numerically investigated by M.S and Venkatasubbaiah (2020) for nanofluids consisting of various nanoparticles, including Al 2 O 3 , SiO 2 , Cu, Fe, diamond and Ag, dispersed in water were used as the working fluids.…”

Purpose The purpose of this study is to do a numerical analysis of the jet to a body filled with phase change material (PCM). The melting of the PCM filled body was investigated by the hot jet flow. Four different values of the Reynolds number were taken, ranging from 5 × 103 = Re = 12.5 103. Water, Al2O3 1%, Al2O3 2% and hybrid nanofluid (HNF; Al2O3–Ag mixture) were used as fluid types and the effects of fluid type on melting were investigated. At 60 °C, the jet stream was impinged on the PCM filled body at different Reynolds numbers. Design/methodology/approach Two-dimensional analysis of melting of PCM inserted A block via impinging turbulent slot jet is numerically studied. Governing equations for turbulent flow are solved by using the finite element method via analysis and system fluent R2020. Findings The obtained results showed that the best melting occurred when the Reynolds number increased and the HNF was used. However, the impacts of using alumina-water nanofluid were slight. At Re = 12,500, phase completion time was reduced by about 13.77% when HNF was used while this was only 3.93% with water + alumina nanofluid as compared to using only water at Re = 5,000. In future studies, HNF concentrations will change the type of nanoenhanced PCMs. In addition, the geometry and jet parameters of the PCM-filled cube can be changed. Originality/value Effects of impinging jet onto PCM filled block and control of melting via impinging hot jet of PCM. Thus, novelty of the work is to control of melting in a block by impinging hot jet and nanoparticles.

Bu çalışmada, bir binaya ait farklı duvar tipleri için ısı akısı analizleri gerçekleştirilmiştir. Bu amaçla kalsik duvar, 1, 5 ve 10 cm cam yünü yalıtımlı duvar modellerinin ısı akısı değerleri incelenmiştir. İlk olarak 2 cm dış sıva, 20 cm tuğla ve 2 cm iç sıva olacak şekilde klasik duvar modeli ve daha sonra yalıtımlı duvar modelleri için analizler Matlab yazılımı kullanılarak yapılmıştır. Manisa iline ait ortalama sıcaklık değerleri Meteoroloji Genel Müdürlüğü verilerinden alınmıştır. İç sıcaklık değeri 21 °C olarak kabul edilmiştir. Bu koşullar altında yapılan analizlerden ısı akısı değerleri karşılaştırılmıştır. Analizler sonucunda 10 cm cam yünü yalıtımlı duvarın ısı akısı değerlerinin, diğer duvar modellerine göre daha iyi sonuç verdiği gözlemlenmiştir.
