摘要
Abstract
In this paper,the engine room ventilation system is analyzed numerically by utilizing the CFD method,and the optimization design of the marine surveillance ship ventilation is also presented to solve the problem of uneven distribution of airflow,large flow speed gradient,and higher temperature for certain operation and activity areas within the engine room. Specifically,by analyzing typical iso-surfaces, me-chanical inflow is changed to mechanical outflow, which increases the air flux by fifty percent, eliminating the airflow whirlpool and improving the airflow under proper negative pressure conditions. Furthermore,an inlet set is added on the starboard side to better eliminate the whirlpool and reduce the local temperature. All in all,the optimization design successfully meets the specification requirements and is seen to be easi-ly applicable,which is instructive to future engineering design.关键词
