Area of Science:
- Fire Safety Engineering
- Fire Dynamics Simulation
- Building Fire Investigation
Background:
- Nighttime inn fires pose significant risks of casualties.
- Taiwan experienced its most severe inn fire incident, necessitating a thorough investigation.
- Understanding the dynamics of such fires is crucial for preventing future tragedies.
Purpose of the Study:
- To analyze the deadliest inn fire case in Taiwan's history.
- To reconstruct the fire scene using advanced simulation techniques.
- To identify the factors contributing to the high number of casualties.
Main Methods:
- Utilized official fire investigation reports and NFPA921 regulations.
- Employed the NIST Fire Dynamics Simulator (FDS) for fire scene reconstruction.
- Analyzed personnel evacuation times and fire hazard factors.
Main Results:
- The FDS simulation successfully reconstructed the fire scene.
- Analysis clarified the reasons behind the exceptionally high casualty rate.
- Evacuation times and hazard factors were identified as critical elements.
Conclusions:

01:12Design Example: Flow Through a Fire Extinguisher
A fire extinguisher that uses pressurized water relies on fluid dynamics principles to generate a high-velocity stream capable of suppressing flames. The water is stored at a much higher pressure inside the extinguisher than the surrounding atmosphere. This pressure difference forces the water to flow rapidly when the extinguisher is activated, and the behavior of the water as it exits the nozzle can be understood using fundamental equations of fluid dynamics.

01:10Reconstruction of Signal using Interpolation
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next sampling...
