초록

The stealth technology, minimizing combat ships’ heat radiation and
sound level in order to avoid detection and attack from enemy, is
gaining its importance these days. Even though there have been
introduced some systems to detect and intercept enemy, the infrared
signature guidance system is most widely used for this purpose.
Therefore minimizing their infrared signature of combat ships is the
first step to improve its survivability at wartime.
The purpose of this paper is to introduce the infrared signature
suppression technology which has been applied by some industries and
study the chances of cooling down its exhaust gas temperature with air
injection. To achieve this goal, a commercial「Computational Fluid
Dynamics(CFD)」code has been adapted and its basic study has been
conducted. With the development of computing skills, the「CFD」has
been widely used to predict performance in the early stage of
development. After studying several cases, we can conclude that air
injection can be an alternative to lower the temperature of exhaust gas
from internal combustion engines
