Ventilation analysis for control room in submarine A26

- Abstract
- This thesis represents results from a numerical study of the ventilation system in the control room in the Swedish submarine A26. This thesis's primary focus is to study and examine the performance and efficiency of the current ventilation system. The ventilation system is very critical and crucial in enclosed environments. Many factors and parameters are affected by the installed system. In confined spaces, the system is involved in comparison to other reasonable conditions. Therefore, it becomes essential to study and evaluate the environment to determine and estimate the current distribution of the air that occurs.
The numerical results in this thesis are obtained by computational fluid dynamics (CFD), a software tool used to analyze...

Many factors and parameters are affected by the installed system. In confined spaces, the system is involved in comparison to other reasonable conditions. Therefore, it becomes essential to study and evaluate the environment to determine and estimate the current distribution of the air that occurs.
The numerical results in this thesis are obtained by computational fluid dynamics (CFD), a software tool used to analyze and understand the air movement's different scenarios and flow. A simplified three-dimensional full-scaled cabin room is used to examine different characteristic parameters to determine if the ventilation system's current design fulfills the required thermal comfort and air quality.
In this analysis, the main focus is to present a numerical study of the current design to ensure that the desired indoor climate that is experienced is comfortable. The results in the primary calculation cases achieved thermal comfort was accomplished. The air temperature and velocity were within the required standard, with approximately 19 °C and 0.25 m/s. The temperature and velocity fields, including flow distribution, are all presented and discussed. However, it was found that a limitation of the flow occurs if the ventilation channels were reduced and unevenly distributed when increased. (Less)
