# FIRE CURVES

## MAIN FEATURES

- Selection of an unlimited number of fire curves for each analysis
- Definition of fire curve type (polynomial, logarithmic, etc.) and coefficients (total calorific value, time constant, shape factors, etc.)
- Computation of heat release versus time
- Computation of heat release dot derivative versus time
- Computation of heat release double dot derivative versus time
- Description of water thermal properties, water supply, water cooling efficiency, ambient temperature and fire temperature
- Computation of water specific heat capacity versus temperature
- Computation of water supply heat capacity
- Comparison of results with available field data
- Visualisation of results
- Suitable for designing and testing

## OPTIONS FOR IO OPERATIONS

- Microsoft Excel Spreadsheet Files (xlsx)

## OPTIONS FOR GRAPHICS

- Standard Image Formats (jpeg, tiff)
- Portable Document Format (pdf)

## TEST CASES

Figure 1, Figure 2 and Figure 3 show how fire curves can be significantly affected in their shapes even though total calorific values and time constants are kept constant, while Figure 4 illustrates the water specific heat capacity due to its thermal properties.
