Abstract
We present a similarity analysis of strong turbulent jets directed perpendicularly into
a crossflow. The analysis neglects pressure terms in the governing equations, and
assumes complete similarity in each of two intermediate-asymptotic regions of the
flow: a jet region, where the jet is largely unaffected by the crossflow, and a wake-like
region, where the jet has been deflected well into the crossflow. Scaling laws are derived
for velocity, scalar concentration, and jet trajectory, and show good agreement with
existing experimental data. The structure of the counter-rotating vortex pair implied
by this analysis is significantly different from typical representations found in the
literature.
