Predicting cavitation in fuel pumps

The same mesh was used for both the multiple reference frame and the sliding mesh calculations to achieve mesh consistency between the two models for relative comparison and assessment.

Liquid ring pumps are used in aircraft fuel systems in conjunction with main impeller pumps and serve the function of removing fuel vapor and air from the fuel. Thus, their reliable functioning plays a critical role in the safe operation of aircraft during flight. Read more at http://articles.sae.org/12709.

Boeing examines expanded metal foils for lightning protection of composite structures

A widely used material for lightning strike protection of CFRP structures within the aerospace industry is expanded metal foil (EMF). An issue with EMF is micro cracking of the paint, which can result in corrosion of the metal foil and subsequent loss of conductivity. Read more at http://articles.sae.org/12712.
