AIAA's second Propulsion Aerodynamics Workshop (PAW) was held in 2014 at the Joint Propulsion Conference (JPC) in Cleveland. The participants included representatives from government, academia, industry and commercial vendors of Computational Fluid Dynamics (CFD) tools. The participants used numerical simulations to predict the performance of pre-defined test cases. The purpose is to compare the simulated predictions to experimental results in order to assess the current generation of CFD tools for propulsion aerodynamics. The workshop propulsion applications included a serpentine inlet (S-duct) and a nozzle. For 2014, the inlet involved an S-duct, similar to that from the 2012 PAW, but with the addition of passive flow control vanes. The 2014 nozzle application included a Dual Separate Flow Reference (DSFR) Nozzle. The family of converging nozzles from the 2012 PAW was also reviewed. Lockheed Martin Aeronautics Company (LM Aero) was among the participants from industry, and provided results for the inlet and nozzle applications. LM Aero was invited to discuss perspectives on simulating propulsion applications. This paper includes a summary of LM Aero's nozzle simulations, as well as a discussion of adaptive gridding for relevant applications. Figure 1 depicts the nozzle geometries for the Propulsion Aerodynamics Workshop. The inlet is discussed in a companion paper.
