Assignment Details
Smoke control design for large areas, and complex structures are challenging especially in Malls, Auditorium, Theatre, Car parking etc. Usually, hand calculation methods are used by engineers to design the smoke control system where the major parameters considered are smoke extraction rate, capacity; size, etc. However, the accuracy of these designs during an actual fire condition is of question especially considering safety of occupants in terms of tenability condition.
In this assignment, you will be provided with a floor plan in the appendix (2). For measuring dimensions of the floor plan, print the same on an A4 paper & choose the appropriate scale indicated against your name given in appendix - 1.
Each level of the atrium is 5-meter-high and total height of atrium for your respective assignment will be specified in appendix - 1.
You will be required to do THREE tasks for this assignment.
You have to perform the smoke control system design especially for the atrium. Refer to the provided floor plan for details of the atrium and other connected areas of the building.
The atrium connects several levels, however the height of the atrium for each student will vary and height of the atrium and its connected levels are appended in this assignment brief.
Assessment Task - 1
You have to develop a fire scenario for your atrium including type of fuel and its properties. The fire will be designed as t-squared fire using fuel properties to calculate smoke production and species concentration. In this task, you have to use species concentration data and conduct tenability analysis including effect of toxic gases, thermal radiation and visibility. Please elaborate in the report any assumption you use for this part.
Assessment Task - 2
You have to define criteria for designing smoke control systems in terms of exhaust and ventilation of smoke from and into atrium, using tenability design. Calculate the smoke exhaust design (extract capacity, size, make up air provision etc.) for your respective atrium dimensions using hand calculation methods as prescribed in the NFPA 92.
Assessment Task - 3
Perform a Computational Fluid Dynamics (CFD) analysis of the smoke control system design that you developed and evaluate its performance per the current applicable codes, standards and international best practices. In this part, you have to run simple FDS simulations to appraise the effectiveness of your smoke management strategy.
Note:
The important parameters and inputs for the engineering analysis must clearly be presented in the report and make sure they are deemed appropriate and conservative in terms of
1. Selection of a relevant fire engineering analysis.
2. Setting desired Goals and Objectives from the proposed analysis.
3. Listing the parameters that need to be considered in the proposed analysis.
4. Acceptance criterion to be followed for the proposed analysis.
5. Assumptions and Limitations of the proposed analysis.
