Transonic Flow at a Slotted Test Section Wall.

Abstract

The objective of the now concluded research has been to make possible the accurate computation of slotted walls interference in transonic wind-tunnels. This has been achieved through studying experimentally the flow at and through slotted walls and through developing theoretical models for such flows. The final result is a homogenous wall boundary condition to be used when computing numerically the three-dimensional transonic flow around a wind-tunnel model, be it to determine the interference from the test-section walls or to adjust the wall parameters for zero interference. The boundary condition is of rather general applicability, admitting great freedom in the choice of slot geometry and facilitating the inclusion of corrections for viscous effects, such as disclosed by the experiments.
