Heat management in sonochemical reactor using fins-PCM integrated system: Unveiling the influence of the sonicated volume

Journal of Engineering Research, Год журнала: 2024, Номер unknown

Опубликована: Янв. 1, 2024

With the purpose of enhancing heat management in ultrasonic reactor, present innovative research aims at exploration thermal behavior sonochemical reactor integrated with fins and phase change material (PCM), focusing on influence different liquid heights (LH). The performance this combination (i.e., sonicated water, fins, PCM) is investigated for first time consideration water volume variation. interplay between height transfer efficiency explored through detailed numerical analysis temperature profiles, PCM melt fractions, enthalpy distributions. investigation has been conducted using a validated CFD model implemented ANSYS Fluent® software. results highlight significant role accelerating melting process improving within reactor. Notably, facilitates efficient conductive during early stages melting. At t = 1000 s, percentages 22.2%, 32.6% 30% were attained compared to 15%, 18% 22% (without fins), LH 5.1, 10.2 15.3 cm, respectively. Therefore, cm showcased 43.5% improvement specific point (1000 s). Moving forward 2000 most favorable achieved resulting percentage increase 66% (with fins) 44% fins). Besides, inclusion increases 32.56% (5.1 cm), 57.6% (10.2 cm) 14.4% (15.3 enthalpy, while declined by approximately 4 K cm. These outcomes indicate clearly importance from irradiated surrounding annular space

On the effect of nanoparticles in different PCM configurations in the thermal performance of a packed bed energy storage system

Results in Engineering, Год журнала: 2024, Номер 23, С. 102441 - 102441

Опубликована: Июнь 21, 2024

When it comes to storing energy and releasing when needed, packed bed storage systems are considered be one of the most efficient available. This paper studies thermal performance melting process in a system using spherical capsules through CFD modeling. The effective model was used simulate fluid flow enthalpy porosity method solve phase change material (PCM) domain. were filled with three various types materials, while water utilized as heat transfer fluid. Due importance configurations materials beds, effects layouts them on investigated. Moreover, Al2O3 nanoparticles cheap easily available added materials. Also, inlet rate (HTF) examined. According results, positioning decreasing order temperature direction is able decline charging time by about 1600 seconds increase efficiency 6.8%. addition decrease 1900 best case system's 7.5%. Increasing HTF from 2.5 10-5 5 (1.5 3 Lit/min) reduced 1800 seconds.
