Irreversibilities reduction of a flow distribution system by means of the EGM methodology
The present work reports the results of an entropy generation analysis on a symmetric flow distributor. The entropy generation minimisation method (EGM) was applied in order to lower the intrinsic irreversibilities associated to the geometric configuration of the flow pattern, aiming to improve the uniformity of flow distribution. 3D Computational Fluid Dynamics (CFD) methods were used to simulate the flow conditions, including a local entropy generation model. The implementation of the entropy generation minimisation method enabled to achieve a significant optimisation of the original design.
