SUMMARY:The impact of surface roughness geometry on aero-engine intakes at

DESCRIPTION:Shock Wave-Boundary-Layer Interactions\, or SBLI's\, are known
  to form on engine inlets within a complex transonic flow-field during typ
 ical take-off and climb configurations. \nOn the engine inlet\, there are 
 a number of potential sources of surface roughness\, such as novel de-icin
 g and acoustic systems\, or surface contamination. The impact on the flow-
 field structure\, as a result of this roughness\, may lead to detrimental 
 side effects\, such as losses in engine efficiency or intake flow stabilit
 y. Previous research into two-dimensional roughness shapes demonstrated fl
 ow-field changes\, for example a thicker downstream-boundary layer compare
 d to a smooth surface. This seminar compares the impact of a two-dimension
 al ridge roughness to a three-dimensional cubed roughness on the inlet flo
 w-field.\n
