Optimization of a Heat Recovery System

iChrome’s optimization solution Nexus, has been used by Vortice, a leading ventilation systems manufacturer, to optimize the aerodynamic performances of a flow deflector for a Heat Recovery System. The main objective of the work was to improve the initial geometry of the deflector in order to achieve optimal flow uniformity at the outlet while reducing the pressure drop across the component.

Nexus has been used to directly integrate Solidwork, for the generation of the geometry, and Ansys CFX, to define and solve the CFD model. The search of the pareto-optimal solutions has been guided by Nexus implementation of Multi Objective Genetic Algorithm (MOGA).

The pareto front, result of the optimization, has allowed the identification of two optimal geometrical configurations, the first one with an improvement of 10% in flow uniformity and the second one with a total reduction of 16% in pressure drop over the initial design.
