CFD Application in Airflow Field Analysis for LNG Ship Engine Room

摘要

For the safety design requirement, analysis of the airflow field withinrnLNG ship engine room is necessary. The CFD analysis for equipmentrnwithin the engine room is a complex calculation problem due to qualityrnand efficiency. This paper provides an easier method to check therndesign of ventilation system. Species transport model is adopted tornsimulate methane-air mixture. Several conclusions are given includingrnvelocity maps. CFD simulation of ventilation test is proposed here torngive out a clearer view of airflow distribution.
