Abstract

The effect of geometry on the performance of a corrugated double-pipe heat exchanger with a hot inner tube was thoroughly investigated. The optimized exchanger geometry was determined by the Response Surface Methodology (RSM). Firstly, heat transfer parameters were numerically obtained using the finite volume method for various hot tube geometries, namely spiral, circular, cylindrical, spherical, and close-packed semi-cylindrical winglets. The maximum thermal performance was exhibited in Re= 400 for spiral fin, equal to 1.82. Secondly, the spiral inner tube was modeled to analyze the number of fins and the fin pitch. The RSM was subsequently employed to analyze for different velocities various geometries featuring 0–4 fins and fin pitches in the range of 300 mm to 600 mm. Also, to enable a more comprehensive application of the results, a statistically obtained accurate relation is presented for the convective heat transfer coefficient in terms of the number of fins, fin pitch, and flow velocity. By performing optimizations using various geometries with different boundary conditions for the first time, this article can serve as a solid base for heat exchanger selection.

使用 RSM 的翅片波纹换热器的统计分析和形状优化

摘要

彻底研究了几何形状对带有热内管的波纹双管换热器性能的影响。优化的换热器几何形状由响应曲面法 (RSM) 确定。首先,使用有限体积法对各种热管几何形状(即螺旋形、圆形、圆柱形、球形和密排半圆柱形小翼)的传热参数进行数值计算。最大的热性能表现在 Re= 400 为螺旋翅片,等于 1.82。其次,对螺旋内管进行建模,分析翅片数量和翅片间距。随后采用 RSM 分析具有 0-4 个翅片和 300 毫米至 600 毫米范围内的翅片间距的各种几何形状的不同速度。此外,为了更全面地应用结果,根据翅片数量、翅片间距和流速,对对流传热系数提供了统计上获得的准确关系。通过首次使用具有不同边界条件的各种几何形状进行优化,本文可以作为换热器选择的坚实基础。
