Data driven forecast of droplet combustion

Detailed Numerical Simulation of Droplet Combustion

Auto-ignition and combustion of single fuel droplets of methanol, n-heptane and iso-octane are studied. The numerical simulations are based on a detailed vaporization model, a detailed transport model and detailed chemical kinetics. The governing equations of the two phases are solved in a fully coupled way. The influence of different physical parameters like droplet temperature, gas phase temp...

Interaction Effects during Droplet-stream Combustion

Forecast Research of Droplet Size Based on Grey Theory

The droplet size can influence the application of a spray system. We apply grey theory in establishing a model of forecasting droplet size. The example used in this study shows that this method is precise in forecasting the droplet size, and is helpful to choose the other parameters of a spray system within a certain droplet size.

DNS of droplet evaporation and combustion in a swirling combustor

Turbulent multi-phase combustion is encountered in a number of engineering applications, such as internal combustion engines and gas-turbine aircraft engines. Therefore, the ability to perform accurate numerical simulations of these systems is of paramount importance to improve their design and efficiency. However, the underlying physics of spray combustion are extremely complicated. The liquid...

Effects of Modeling Assumptions on Black Liquor Droplet Combustion

There are many assumptions that have been considered when describing black liquor droplet combustion. These include assuming an isothermal particle, a constant diameter particle, inert inorganic species, and one-film diffusion model. This paper shows the effects of systematically relaxing these factors for a 1-D spherical model for black liquor combustion. The flame is described using boundary ...
