• Numerical Simulations of High Temperature Jets from the Main Propulsion System and Auxiliary Power Unit Impinging Against a Construction of the Passenger Plane
    Newly designed passenger aircraft should meet safety and reliability requirements in imaginable emergency situations, one of which is the burn-through of a combustion chamber body of the main propulsion system (MPS) and of the auxiliary power unit (APU), both on the ground and in-flight. In accordance with the international safety standards, an emergency case is investigated using STAR-CCM+ and Abaqus in which, due to local disruption of the combustion...
  • The AIAA Propulsion Aerodynamics Workshop (PAW) brings together CFD users from industry, government and academia with the goal of developing best practices for the simulation of propulsion-specific flows. In its two iterations, the workshop has focused on two flows, the serpentine duct (s-duct) and the nozzle. For the s-duct, we examine the role of mesh and turbulence models for cases with and without vortex generators to understand how to best tackle the...
  • Presented at the Aerospace, Defense and Marine 2009 Conference
  • STAR-CCM+ is unrivaled in its ability to quickly and efficiently tackle complex geometries. Shown is an analysis with STAR-CCM+ displaying the complex flow patterns as a result of the accidental deployment of a thrust reverser on a business jet while in-flight.
  • Analysis of fan blades of propulsive wing UAV.
  • At the heart of STAR-CCM+’s post-processing toolset is the ability to extract and analyze engineering data. Here, an harmonic balance (HB) simulation was performed on a multistage axial compressor and the relative Mach mumber on the blades was displayed.

As the demand surges towards greater fuel efficiency, quieter aircrafts, lesser emissions and reduced cost/passenger seat/km, innovation is driving the propulsion systems design of today to deliver these results. Be it basic turbomachinery performance, combustion, rotor/stator interaction, plume analysis or erosion, the physics capabilities of STAR-CCM+ are well suited and validated to cover all these areas. Technologies like the Harmonic Balance Method, FW-H aeroacoustic prediction model, Digital Analysis of Reaction Systems (DARS) and Multidisciplinary Design eXploration (MDX) with HEEDS are all complementary to propulsion system analysis within STAR-CCM+.
