CFD Simulation of Airflow Organization in the Ship Accommodation

摘要

Efficient ventilation and sound air current are significant to improve indoor air quality (IAQ) and control the contamination concentration. Healthy and comfort air conditioning will provide a strong guarantee for high-performance work. While limited by lots of conditions, the airflow distribution in room is very difficult to be revealed, so numerical simulation and analysis for airflow organization become more and more important during the design stage of ventilation and air conditioning system. In the paper a ship accommodation is taken as a model to do simulation analysis on the effect of different airflow organizations. On the basis of computational fluid dynamic (CFD) theory and methodology, the temperature fields, velocity fields and air age fields under different airflow organizations are gotten by means of Airpak3.1. All these search works will be helpful for the further design and optimization for the ventilation and air conditioning system of the ship accommodation.
