CFD in the Aerospace and Aeronautics Industries

Abstract

When we think of CFD (computational fluid dynamics) in the aerospace and aeronautical industries, we often limit our thinking to the aerodynamic analysis of wing/tail structure or fuselages. But CFD analysis applies to almost all of the critical components and systems of an aircraft. For example, excessive heat in the electronic components can lead to failure and reliability issues. Fuel delivery and engine cooling systems must be optimized. Cabin air conditioning/heating systems need to be analyzed. And the industry cannot afford to either over-conservatively design these systems (excessive cost) or prove efficiency/reliability by building multiple physical prototypes, testing in labs, and then re-designing, which is a long and expensive process. Because of these issues, CFD comes into play early and throughout the design process for multiple components and systems in the aircraft.
