摘要
Abstract
To investigate the performance improvement of the DNF plate type in air preheat-ers/flue gas heat exchangers,Design of Experiments(DOE)was employed to optimize the structural parameters.A three-dimensional parametric model of the DNF plate type was established using 3 D software,and its heat transfer coefficient and resistance coefficient were analyzed using Computational Fluid Dynamics(CFD)software.Numerical optimization of the structural parameters of the DNF plate type was conducted using DOE,resulting in a 6.7%increase in the heat transfer coefficient and an 8.0%increase in the resistance coeffi-cient.Numerical analysis verification indicates that the performance of the optimized DNF plate type aligns with the DOE predictions,and its application in engineering projects is expected to yield significant economic benefits.This study demonstrates a lean design optimi-zation method for engineering designers.关键词
