We are a smoke control damper producer. Aerodynamic properties are a very important feature of the product.
The project is to simulate in a first attempt 2 dampers which have been measured physically. Comparison between actual data and simulated data will allow us to evaluate the simulation work. In a later stage, upon positive evaluation of the simulation work, many more CFD's will be needed.
Simulation of the airflow trough an open damper to derive the pressure drop as a function of the airflow through the damper.
There are two damper dimensions to simulate, a 200 x 200mm damper and a 1000 x 200mm damper. The damper has 2m of airduct upstream and downstream. Each simulation of airflow through the duct system should be performed with and without the damper included.
For each airduct size, we suggest to simulate four setpoints of airflow velocity e.g.(2 m/s – 6m/s – 8m/s – 15m/s). This makes a total of 8 simulations for each duct.
The results should be presented as in figure 5 of standard EN1751 (can be supplied if necessary)
• Air temperature: 20 °C
• Atmospheric pressure: 101325 Pa
• Air density: ~1.2kg/m³
• Maximum air velocity through the airduct: 15m/s
