Abstract
The superior efficiency of the piecewise linear approximation method based on Delaunay triangulation has been demonstrated. This method completely eliminates negative concentration values on the resulting surface and exhibits the most favorable gradient distribution, with only 3.33% of gradients exceeding 75 ppm across the entire point cloud surface. The significance of the obtained results lies in the confirmed ability of this approximation method to generate highly reliable and physically accurate regime maps. These maps are essential for predicting critical emission levels, such as carbon monoxide (CO) and nitrogen oxides (NOx), during liquid hydrocarbon fuel combustion, enabling the development of effective burner optimization strategies to minimize environmental impact and maximize combustion efficiency in practical power installations.
