This paper explains how Concurrent Computational Fluid Dynamics (CFD) technology has become a cornerstone for aerospace mechanical design today. Designers must perform flow analysis on a broad range of components and subsystems such as hydraulic values and cockpit ventilation systems. Almost all aircraft elements that come into contact with liquids or gases or that conduct heat from a device will require fluid flow analysis. Thus, flow analysis will help engineers save cost, time and weight in their aerospace system design by revealing hidden design weaknesses and enabling the designer to optimize the design for greater performance.
