Calculator Description
Explosions Calculator v1
Explosions calculates the thermodynamic properties of a pressure wave generated by an explosion.

Explosions

Subject

An explosion will occur as a result of the sudden release of energy from a chemical (incl. atomic) reaction or high-pressure gas. This sudden release of energy will generate a pressure wave within a surrounding fluid that will radiate rapidly, locally increasing atmospheric temperature and potentially damaging property and/or personnel.
Note: no pressure wave can be generated in a vacuum.

In order to provide suitable protection from such an event it is necessary to evaluate the properties of the pressure wave and provide suitable protection from the expected overpressure in the form of apertures and vents and/or the relocation of vulnerable objects.

Calculator

Explosions calculates the thermodynamic properties of a pressure wave generated by an explosion according to the Sadovsky model and a thermodynamic model, both of which work from the same input data and provide the same output.

Explosions also provides a co-ordinate listing for time, pressure, velocity, temperature and NFPA’s deflagration index for you to copy and paste into your preferred spreadsheet and plotting with respect to the radial distance from the explosion centre.

Output data from the explosions calculator can be used in CalQlata’s Vents program.
