The committee identified key concerns regarding the NRL modeling approach and experimental methods in three categories: 1. Gaps in the study approach and the assumptions chosen to represent the physical system of wellhead combustion limit the utility and accuracy of the approach and the model.

Specifically, the soot characteristics for crude oil are not encompassed by n-heptane, and sooting propensity will affect several critical physical and chemical transport mechanisms in the model, including the radiative energy balance. In addition, preferential evaporation of lighter components in crude oil may induce composition and thermal stratification in the mixture, affecting combustion rates, which are not captured by heptane, and CFD mixing and combustion models need to account for stratification.

To this end, identifying better unit problems to frame such a research program will require more substantive understanding of the underlying conditions of wellhead combustion, as well as the goals for the stakeholders of such work. 1 National Snow & Ice Data Center.
