Abstract

Purpose

This study aims to propose a new composite metal fin structure to enhance heat transfer efficiency during the phase change energy storage (PCES) process in a hot water oil displacement system.

Design/methodology/approach

PCES numerical unit is developed by varying the radii of annular fins and the number of corrugated fins. The impact of the finned structure on melting characteristics, energy storage performance and rate of heat storage is analyzed.

Findings

This study indicate the presence of non-uniform melting behavior in PCES unit during the heat charging process, which can be mitigated by increasing the number of corrugated fins and the radius of annular fins.

Originality/value

The impact of the finned structure on melting characteristics, energy storage performance and rate of heat storage is analyzed. This study indicates the presence of non-uniform melting behavior in PCES unit during the heat charging process, which can be mitigated by increasing the number of corrugated fins and the radius of annular fins.

复合翅片结构热水驱油系统相变储能过程研究

目的提出一种新型复合金属翅片结构，以提高热水驱油系统相变储能（PCES）过程中的换热效率。设计/方法/方法pces数值单位是通过改变环形鳍的半径和波纹鳍的数量来开发的。分析了翅片结构对熔体特性、储能性能和蓄热速率的影响。研究结果表明，PCES装置在装热过程中存在不均匀熔化行为，可以通过增加波纹翅片的数量和环形翅片的半径来缓解这一现象。分析了翅片结构对熔体特性、储能性能和蓄热速率的影响。研究表明，PCES装置在装热过程中存在不均匀熔化行为，可以通过增加波纹片的数量和环形片的半径来缓解。
