A Numerical Study of the Multi-Component Effects on the Combustion and Evaporation of Biofuels and Blends
… A multi-component droplet evaporation model, as efficient as a traditional zero-dimensional model, yet preserving the correct description of the underlying physical process is developed in this study. The continuous thermodynamics formulation is used, for which the fuel (or liquid …

Analysis of energy balance in a helicon coupled to an inertial electrostatic confinement device
… tube was determined. To build upon this COMSOL model which contained no plasma, calculations of the theoretical ion flow rates were performed. These calculations used the measured ion current to determine the ionization fraction. Using the ionization fraction as an input into the zero …

A Five-Zone Model for Direct Injection Diesel Combustion
… imaging studies have provided a new conceptual model of the internal structure of direct injection diesel fuel jets as well as empirical correlations predicting jet development and structure. This information was used to create a diesel cycle simulation model using C language including …

Modeling and simulation of multi-component condensed phase combustion at the meso-scale
… develop a framework for continuum multicomponent modeling of energetic materials with applications to condensed phase combustion at the meso-scale. The meso-scale is defined to be on tens nano-meters to hundreds microns where physically distinct features, including crystal grains, defects, …

Modelling the speciation and biogeochemistry of iron in oceanic surface waters at the Bermuda Atlantic Time-series Study site
By means of numerical modelling the cycling of iron between its various physical (dissolved, colloidal, particulate) and chemical (redox state and organic complexation) forms in the upper mixed layer of the ocean is analysed. Using the model an initial quantitative assessment is made of how this …

A thermofluid network-based methodology for integrated simulation of heat transfer and combustion in a pulverized coal-fired furnace
… problem requires a thermofluid process model that can simulate the water/steam cycle and the coal/air/flue gas cycle for steady-state and dynamic operational scenarios, in an integrated manner. The furnace flue gas side can be modelled using a suitable zero-dimensional model in a …

A numerical study of the multi-component effects on the combustion and evaporation of biofuels and blends
… 3) to develop a new droplet evaporation model using the continuous thermodynamics formulation, which is capable in accommodating multiple distribution functions, accounts for preferential evaporation, finite diffusion and surface regression of the droplet; 4) to demonstrate the …
