So, the problem is to avoid rusting the roof and wall of the room from the evaporated water, especially when room is completely closed. It is very essential to extract the evaporated fluid from the room and fresh air to be supplied uniformly over a large span of the domain.
One of our clients wanted us to design an effective ventilation system with the help of flow simulation (CFD Analysis). In the existing design, there were 12 louvers and 6 fresh air fans but the results in very poor air distribution and ACPH value is 2 i.e. not adequate for human comfort.
We analysed the existing design for which we prepare a 3D model in SolidWorks and CFD analysis in Ansys Fluent. It helps us to find out the flow behavior and flaws in the design. Followings are the finding:
- Many dead zones where velocity is less than 0.25 m/s.
- Poor air distribution
- No arrangement for the exhaust
- ACPH is very low
Recommendations were made to change the location of the fans. We replaced the fresh air fans with exhaust fans. Optimized the design of the louvers. Implementing the changes, flow distribution improved a lot with a higher air change rate.
Changes made in the design backed with another simulation iteration and project is successfully implemented on the site. Efforts taken by our technical team results in a happy client.
