Title: Thermal Performance Enhancement in Aerospace Cavities using Advanced Nanofluid Coolants
Time & Venue: 2026年7月8日（星期三）14：00-15：00 南楼N913
Abstract: This research has emerged from the critical need to understand fluid dynamics and heat transfer analysis in aeronautical engineering where advanced thermal management systems and nanofluid-based coolants are crucial for efficiency and safety. This problem is developed to investigate fluid dynamics and thermal transport process in B-2 bomber aircraft which is an application of aeronautics systems. Our research includes a numerical study of convective heat transport and entropy production analysis in a B-2 bomber aircraft design cavity filled with CNT-kerosene oil based nanofluid subject to internal heat generation. The governing equations for continuity, momentum and energy conservation are discretized by using finite element scheme under steady state constraints. The impacts of few variables including Rayleigh number, heat generation parameter and volume fraction of CNTs on flow structure, temperature distribution and entropy production are analyzed. Computational outcomes reveal that the addition of carbon nanotubes raises thermal conductivity and significantly intensifies convective heat transfer up to 43% and entropy production up to 30%. High heat absorption rates and Rayleigh number raise both temperature gradients and entropy production. Heat generation parameter leads to reduce heat transfer rate up to 29% and entropy production up to 15%. These observations offers valuable insights for optimizing nanofluid-based thermal performance in a B-2 aircraft design cavity under free convection and heat absorption effects.
