The paper discusses a new method to approximate the sometimes missing apex point of the explosion limit curves of flammable substances with diluents in air. The base of the new method is to vary the frame points of the co-monotonic Splines using the de Casteljau algorithm. We show several examples for flammable/inert/oxidizing gas containing systems - selected by the program TRIANGLE - where the method was applied. Due to the definition of the frame Splines it can be stated that the new method never restricts the explosion range around the apex and shifts the explosion limit curve into the direction of higher inert gas concentrations. This means that the new method can correct the highly "cut down nose" of the co-monotonic Splines and gives a more safer explosion range of these systems.
This paper discusses the approximation problems of the explosion range of flammable substances with diluents in air and demonstrates how the different Splines can be applied for interpolation of explosion curves based on measured data points. The methods are tested on many systems which consist of flammable gas/inert gas/oxidizing gas. A comparison of the results gained by applying different Spline-functions and a computer presentation of the results with help of the program TRIANGLE are also given.
