Jr. Carlson et al., COMPUTATIONAL ANALYSIS OF VENTED SUPERSONIC EXHAUST NOZZLES USING A MULTIBLOCK MULTIZONE STRATEGY, Journal of propulsion and power, 9(6), 1993, pp. 834-839
A high-expansion ratio axisymmetric nozzle with and without longitudin
al trailing-edge slots has been examined. Solutions were determined us
ing a three-dimensional Navier-Stokes computer code. These results wer
e compared with experimental data to determine the accuracy of the cod
e for nozzle applications. Additionally, off-body flow physics were ex
amined to understand the changes in nozzle performance with differing
operating conditions. Highly overexpanded and near-design jet exhaust
flows were simulated exhausting into subsonic and supersonic freestrea
m Mach numbers. Pressure and velocity vector flowfields are shown and
the predicted internal nozzle performance is compared with experimenta
l data. Solutions were developed using laminar viscous stresses and th
in-layer approximations.
