An Approach to Determine the Maximum Rate of Pressure Rise for Dust EXPLOSIONA

Abstract:

A new science method called Recursive Fitting Method (RFM) used to calculate the dust explosion rate of pressure rise was introduced. Residual Sum of Squares per Point (RSSR) was introduced to evaluate the fitting goodness of different conditions. Compared with existing methods, the results show that Recursive Fitting Method (RFM) has higher computational accuracy by drawn an experimental curve. And it has better computational repeatability compared with Tangent Method by repeating calculation of the same data. The new method can not only reduce the influence of signal noise but also calculate the correct rate of pressure rise accurately.
