abstract = {This paper investigates the surface heat transfer caused by
interaction of a jet and a supersonic crossflow near the jet
injection hole. A sonic jet with different momentum ratios
(, 1.018, 1.477) was injected perpendicularly into a
crossflow with a Mach number of 3.0 in a supersonic wind
tunnel. Surface temperature through time measured by
infrared thermography was used to deduce surface heat flux.
In addition, heat transfer coefficients and adiabatic wall
temperatures were derived from time histories of surface
heat flux and temperature. In order to consider an effect of
conduction from the inner hole surface, a three-dimensional
energy conservation is considered in the deduction process
of the heat flux. As a result, the characteristics of the
heat transfer near the hole and the change in the heat
transfer with momentum ratios are presented. The separation
vortex and recirculation vortex are found to be dominant
flow features in terms of the augmentation of the heat
transfer. The maximum heat transfer is observed at the
immediate vicinity of the hole due to the flow oscillation
from a jet-mixing layer. This oscillation resulted in a
$390\%$ of augmentation of the heat transfer near the hole
compared to the freestream even at the lowest momentum
ratio. Also, the augmentation near the hole is more
susceptible to change of momentum ratio compared to the
augmentation on the overall interaction area.},
