Fluid Dynamics of Highly Pitched and Yawed Jets in Crossflow

Results from an experimental investigation of flowfields generated by pitched and yawed jets discharging into a crossflow are presented. The circular jet is pitched at a = 20 and 45 deg and yawed between β = 0 and 90 deg in increments of 15 deg. Hot-wire measurements are performed to obtain all three components of mean velocity and turbulent stresses. Cross-sectional surveys are conducted at x = 3, 5, 10, and 20, where the downstream distance x is normalized by the orifice diameter. Data are acquired at momentum-flux ratio, J = 1.5, 4, 8, and 20
