An Investigation of Flush Off-Takes for Use in a Cooled Cooling Air System - (PPT)

摘要

Overall uniformity always decrease with increase in pre-diffusion. Optimisation is required between ramp angle and w/d ratio. Thick B.L inflow improves uniformity during pre-diffusion (Increased 'cs' tube height). High aspect ratio off-take is recommended for better RPR and Uniformity (under prediffusive operating conditions).
