Abstract

The effects of Hull Film Cooling (HFC) water-spray systems on infrared detection have already been presented by Vaitekunas and Kim ([9],[10]). This paper will further assess the impact of zonal Active Hull Cooling (AHC) water-spray systems on the infrared detection of naval ships to ensure its proper usage against a range of infrared-guided anti-ship missiles. The transient performance of such systems will also be assessed using a fully transient version of ShipIR/NTCS which includes a laminar flow water-film convection model to simulate the effects of an activated water-spray. The model can be used to analyse the performance of a proposed design, and adjust the nozzle count to meet a specific requirement. Recent efforts to validate the new model against existing experiments is also described.
