Heat exchange performance evaluation inside a lattice panel using CFD analysis for an innovative aerospace anti-icing system

As the global push for sustainable development intensifies, the aerospace industry is exploring innovative solutions to reduce greenhouse gas emissions and optimize resource consumption. This paper investigates the performance of an advanced anti-icing system that integrates an onboard function within the primary structure of an aircraft, offering potential reductions in weight, cost, and energy consumption. To evaluate the heat exchange performance of this innovative system, we examine various lattice structures featuring different cell topologies, sizes, and densities. High-fidelity Computational Fluid Dynamics (CFD) simulations are utilized to assess the performance of the constituent cells within the lattice panel, with the goal of identifying the optimal solution that meets design requirements for heat transfer efficiency, pressure, and overall mass of the components. A statistical approach based on Design of Experiments (DoE) is employed to elucidate the relationship between the cell design parameters and the resulting thermal properties. Our findings contribute valuable insights for the development and implementation of advanced aerospace anti-icing systems, supporting the ongoing evolution of sustainable and efficient aviation technologies.
