ABSTRACT

Taguchi method is an experimental design methodology that uses a statistical technique to optimize process parameters while minimizing variability and improving output quality. In this article, Taguchi methodology has been utilized for parametric optimization of the design of a porous triangular enclosure, with an in-line rectangular finned array, to achieve maximum natural convection heat transfer. Three influencing parameters viz. fin spacing (S), percentage volume occupied (V_o) (measure of enclosure porosity), and fin tip to cooling plate distance (d), are optimized with consideration of maximizing the heat transfer (i.e. Nusselt number). The experimental design has been created using Taguchi’s L9 (3^3) orthogonal array. An analysis of variance (ANOVA) table, regression equation, response surfaces, and contour plots have also been generated using Response surface methodology, and the optimum values of influencing parameters have been suggested.

摘要

田口方法是一种实验设计方法，它使用统计技术来优化工艺参数，同时最大限度地减少变异性并提高输出质量。在本文中，田口方法用于多孔三角形外壳设计的参数优化，该外壳具有直列矩形翅片阵列，以实现最大程度的自然对流换热。三个影响参数即。翅片间距 (S)、占用体积百分比 (V _o）（外壳孔隙率的测量）和翅片尖端到冷却板的距离（d），在考虑最大化传热（即努塞尔数）的情况下进行优化。实验设计是使用田口的 L9 (3^3) 正交阵列创建的。还使用响应面方法生成了方差分析 (ANOVA) 表、回归方程、响应面和等值线图，并建议了影响参数的最佳值。
