A comparison of numerical simulation and scheme for hull painting plant ventilation airflow

摘要

The STAR-CCM+ technology is also used to analyze the location and number of vents in hull coating plant in the case of constant air volume. By means of numerical simulation and mathematical model theory, this paper makes a comparison of air distribution in the working area of this plant, and found the interior velocity and temperature field vary with different location and number of vents. Specifically speaking, the lower position and improper number of vents can lead to unevenness of the internal thermal environment and imbalance of wind speed in the working area. This study provides simulated basis and technical references for the better coating operations in suitable environment, which is significant for putting forward the improvement, optimizing the quality of the coating operation and saving energy.
