The deadline for submission is 23:59 on 12 April 2021(Monday).Aims of AssessmentThe module aims to provide students with fundamental knowledge and skills of using computing infire hazard analysis. This includes both essential numerical programming skills required to carry outbasic engineering computations within generic programming environments and application ofspecialist software to solve typical computational problems of fire engineering.Learning OutcomesThis piece of assessment Will test your ability to meet learning outcomes 1-4 as described in yourmodule booklet: -1. Use and apply Scilab to plot graphs of functions given both analytically and by the data fromtext files. Incorporate those graphs into reports electronically2. Apply standard numerical Methods of computational engineering, e.g. curve fitting andinterpolation, solution of simultaneous linear equations, and statistical processing ofexperimental data3. Write Scilab scripts and function to carry out engineering computations and plot complexgraphs4. Demonstrate the use of problem solution tools and evaluative skills in the selection ofappropriate methods of analysisAssignment Details This is an individual assignment. Copying from the works of another personconstitutes plagiarism, which is an offence with the Universitys regulations and willresult in a mark of ZERO for the assignment. This assignment requires the students to complete ALL questions as attached; The word limit is 2500 works (+/- 10%); All the assumptions/definitions, Comments in the scripts and explanation in youranswers should be clearly stated due to be awarded; Submission of all input script files and snapshots of output results are required; and This assignment will carry 50% weighting of the total mark for this module.Submission DetailsThis assignment should be submitted online to Canvas by the deadline given above. Submission ofTurnitin Report is NOT required. Five days rule will be applied for any late submission, i.e. 40% markis capped.Page 2 of 5Assignment Details (Learning Outcome: 1-4)Q1. The architectural layout of the 2-stories building is shown in the sketch as below. Theheadroom of G/F and 2/F is 5 m and 3 m respectively. The multi-function rooms atG/F may involve the usage as assembly hall or exhibition functions. (40 Marks)Each student shall use FDS+Evac to study the occupants evacuation of the wholebuilding Including G/F and 2/F under the following three scenarios.a) Fire Drill Model: No fire is involved. All the exits and staircases are available forevacuation. Detection time is assumed as 0s.b) Evacuation Scenario A – Front entrance at G/F is blocked by fire at T=120s. Fireaffecting area at front Entrance is around 2m*2m close to the door centre. Detectiontime is assumed to be 20s.c) Evacuation Scenario B Upper landing area to the left staircase is blocked by fireat T=60s. Fire affecting area to the left staircase is around 2m*2m close to the exitdoor of meeting room. Detection time is assumed to be 30s.To demonstrate your works, the assignment shall incorporate the below items:Multi-functionRoomFigure 2 – Layout Plan (G/F)20 m14 mNot to scaleFigure 1 – Layout Plan (2/F)Office12 m 8 m5 m 7 m 8 m6 m6 m2 m1m 1mMeetingRoomOffice Office Office Legend:Single leaf exit door0.8m (W) * 2.0m (H)Double leaves exit door1.8 m (W) * 2.0m (H)Multi-functionRoom8 m 8 m1m1m4.5mPage 3 of 5(1) you will have to report the main assumptions of the occupants in each space,occupants profile including pre-movement time assumption, unimpeded walkingSpeed on horizontal floor or downward stairs, etc. for each scenario.(2) FDS+Evac input scripts shall be provided.(3) The simulation results shall be summarized in the RSET table to indicate theclearance time for each room and floor.(4) Evacuation screenshots in every 30 seconds shall be provided.Q2. Consider the set of parametric equations:() = 0.152() = 0.152Create the following plots on the same page:(a) X versus t(b) Y versus t(c) Y versus X(10 Marks)Test Case:Q3. Consider a T-square developing fire with the heatRelease rate (). It is assumed that the design fire willdevelop from ignition to peak heat release rate in a t-squared growth rate and then burn out by a tsquareddecay rate with the same ratio. The profile isillustrated as below:Assume the fire class is labelled asU ultra-fast,F fast,M medium, andS slow.Write a function using Scilab to read the label of fireclass and the developing time (T) from ignition to thepeak heat release rate and plot the heat release rate() vs time . The function shall output the resultsof time and Heat release rate automatically to anexternal file.

The following equations are used to calculate the thermal response of a detector orsprinkler located at or near a ceiling whose area is large enough to neglect the effectsof smoke layer development. When the detector or link temperature reaches itsactivation temperature,Total theoretical fire heat Release rate at time (kW) Radial distance of the detector/sprinkler from the vertical axis of the fire (m) Response Time Index of detector/sprinkler,+Temperature of the jet at the next time step, + (oC),Temperature of the jet at the previous time step, (oC) Ambient space and initial detector/sprinkler temperature (oC),Detector or sprinkler temperature at time, (oC) Detector or sprinkler activation temperature, (oC),Velocity of the ceiling jet gases at the time step, (m/s) Vertical entrainment distance; the difference between the height of the ceiling andthe base of the flames (m)Assume the fire will develop as a t-square growth fire. Four fire classes U ultrafast,F- fast, M medium and S slow will be considered, same as thedefinition in question Q3.Write a Scilab function and define the required input parameters such asdetector/sprinkler information, fire class, initial ambient temperature and time step asthe input arguments for the defined function. Use the above equations to estimate theactivation time of the detector/sprinkler (,) and required heat release rate toactivate the detector/sprinkler. Try to plot the detector temperature (,) , ceiling jettemperature (,) and heat release rate Versus time.
