Design-oriented Sobol’ Sensitivity Analysis Of Key Parameters In Plate Heat Exchanger Optimisation
Original language description
Plate heat exchangers (PHEs) are widely used across industries due to their compactness, high efficiency, and reliability. However, their performance can be substantially improved through targeted design optimisation. This study focuses on optimising a one-dimensional PHE model, validated through both experimental data and CFD simulations. The goal is to enhance thermal effectiveness while minimising pressure drop by adjusting key geometric parameters within feasible limits. A multi-objective optimisation strategy is employed to balance these competing performance goals. To reduce computational effort and improve efficiency, a pre-optimisation sensitivity analysis using Sobol’s method identifies the most influential variables. This allows the design space to be reduced from six parameters to two without compromising accuracy. The channel gap is found to be the dominant factor affecting pressure drop, contributing over 50% to its variation. In contrast, plate thickness has the greatest impact on thermal effectiveness, accounting for more than 40% of the total and interaction effects. These insights enable more targeted design adjustments and demonstrate the value of integrating sensitivity analysis into the optimisation process. Overall, the study presents an effective and computationally efficient approach to improving PHE performance in industrial applications.
