Computational and experimental investigation into aerodynamic interference between slender bodies in supersonic flow [PDF]

open access: yes, 2011
Aerodynamic interference can occur between high-speed bodies when in close proximity. A complex flowfield develops where shock and expansion waves from a generator body impinge upon the adjacent receiver body and modify its aerodynamic characteristics.
