초록

본 연구에서는 해수 분사 기반 표면 냉각 기법이 함정 표면의 열적 거동과 적외선 신호에 미치는 영향을 분석하였다. FF급 함정을 대상으로 열전달 해석과 적외선 신호 해석을 수행하여 해수 분사 유량 조건에 따른 표면 온도 변화 및 적외선 복사 신호 변화를 정량적으로 평가하였다. 해석 결과 해수 분사 적용 시 표면 온도가 감소하며 이에 따라 중적외선 및 원적외선 영역에서 적외선 신호가 감소하는 경향을 확인하였다.

Abstract

This study investigates the effects of seawater spray cooling on the thermal behavior and infrared signature of ship surfaces. Thermal analysis and infrared signature simulation were conducted for an FF-class naval ship to evaluate the variations in surface temperature and infrared radiance under different seawater spray flow conditions. The results show that applying seawater spray cooling reduces surface temperature and consequently decreases infrared emissions in both MWIR and LWIR bands.
