Original abstract
At present period the application of complex models based on computational fluid dynamics (CFD) increases. At the same time, the cost of full experiments with high number of factors grows rapidly. In some cases, however, experimental approach cannot be fully substituted by computational modeling, which applies also to tuning of design of new burners. Due to high cost of experiments therefore grows the importance of their proper design and statistical data analysis. The application of statistical methodologies leads to the determination of key product design parameters that control its performance. The present work presents an experiment from its preparation and planning, preliminary considerations about the model and implementation of the experiment, to its subsequent evaluation. Furthermore, we point out the problems of performing full experiment with high number of factors, which would be expensive and time consuming, and outline the possibilities of creating the basis for fractional experiment. The experiment presented in this work is carried out at an up to date experimental facility for testing diffusion gas burners. The investigation focuses on the influence that burner design parameters have on the formation of nitrogen oxides. Priority is however always given to the functionality of the burner (namely flame stability).
Czech abstract
V současné době stále roste význam použití komplexních modelů založených na počítačovém modelování (CFD). Současně náklady spojené s provedením plného experimentu s vysokým počtem faktorů neúnosně rostou. Avšak v některých případech nelze experimentální přístup zcela nahradit počítačovým modelováním, které je využíváno při optimalizaci návrhů konstrukcí nových hořáků. Z důvodu vysokých nákladů na provedení experimtů stále více roste význam správně naplánovaných experimentů a statistické analýzy. Aplikace statistických metod vede k určení klíčových parametrů produktu, které ovlivňují jeho funkci. Prezentovaná práce se zabývá vlastním naplánováním a provedením experimentu s následnými úvahami o modelu a vyhodnocením naměřených dat. Mimoto jsme poukázali na problémy spojené s provedením exprimentu s velkým počtem faktorů, které by bylo velmi finančně i časové náročné, a nastínili jsme možnosti vytvoření zkráceného experimentu. Experiment byl proveden na moderní zkušebně hořáků a byl zaměřen na vyšetření vlivu konstrukčních parametrů hořáku na tvorbu oxidů dusíku. Avšak priorita byla stále kladena na funkčnost hořáku, jmenovitě na stabilitu plamene.
