Abstract

The latest version of ShipIR/NTCS (v4.3) includes a more generalized 4-point (quad) element type that not only reduces the total number of surface elements in the ShipIR model, but also delivers a higher-quality coarse wall boundary mesh on which to construct the coupled CFD wall boundary and volume meshes for use in CFD analysis. The objective of the current paper is to explore the impact of these improvements on the coupled ShipIR / ANSYS Fluent CFD model solutions previously discussed for both naval ships (Vaitekunas et al, 2011) and aircraft (Vaitekunas 2022). In the case of the naval ship, methods and inputs used to characterize the exhaust gas plume trajectory and associated risk of plume impingement on specific areas of the superstructure are described and applied to a coupled ShipIR / ANSYS Fluent CFD model of the CFAV Quest. These techniques are used during the detailed design phase of a new warship to help further reduce the risk of combat system equipment failure and/or elevated thermal IR signatures associated with exhaust gas impingement heating.
