Numerical Prediction of Low Heat Rejection Diesel Engine Performance for Small Size Vessel

시뮬레이션 프로그램에 의한 소형 선박용 저열손실 디젤엔진의 성능평가

It is known that over 60% of engine power is dissipated into circumstance, cooling water and cooling oil without any conversion into useful work. Following the first law of thermodynamics, it is possible that heat loss to cooling water can be converted into mechanical work through crankshaft. But in case that the engine is operating without any cooling effect, the serious problem unsolved so far is the engine durability. In this study, LHR(Low Heat Rejection) engine was introduced as one of the promising engine and several useful qualitative and quantitative data were drawn.
