Raghavan, V., Gogos, G., Babu, V. and Sundararajan, T., â•œEffect of Gravity on Methanol Diffusion Flames Burning within a Forced Convective Environmentâ•š, accepted for publication in International Communications in Heat and Mass Transfer (2006)
Characteristics of methanol diffusion flames burning under three different configurations with respect to the directions of forced and natural convective flow fields are presented for zero and normal gravity conditions. Combustion of a spherical methanol particle and of a methanol film within a mixed convective environment, have been numerically simulated. The effects of gravity on aiding, oppo...

A numerical investigation of unsteady liquid fuel droplet combustion with droplet heating and internal circulation under forced convection is presented. The droplet is burning within an airstream at atmospheric pressure and under zero-gravity conditions. Combustion is modeled using finite rate kinetics and a one-step overall reaction. The numerical model includes a new multicomponent formulatio...
متن کاملEffects of Forced Convection and Surface Tension during Methanol Droplet Combustion
A numerical investigation of surface tension and forced convection effects on moving and suspended methanol droplets burning in a zero-gravity, low-pressure air environment is presented. Simulations were conducted using a predictive, transient, axisymmetric model for an initial droplet diameter of 0.5 mm, an ambient temperature of 1200 K, and initial Reynolds numbers (Re0) in the range of 1 to ...
متن کاملPope, D. and Gogos, G. "Numerical Simulation of Fuel Droplet Extinction Due to Forced Convection," Combustion and Flame, 142:89-106 (2005)
The extinction of an envelope flame at the forward stagnation point of a liquid fuel droplet due to forced convection is numerically investigated. The droplet is oxidizing within an air stream at atmospheric pressure. Combustion is modeled using finite-rate chemical kinetics and a one-step overall reaction. The gas-phase solution is obtained using the quasi-steady equations of mass, momentum, s...
متن کاملA New Multicomponent Diffusion Formulation for the Finite-volume Method: Application to Convective Droplet Combustion
A new multicomponent formulation, appropriate for use with the finite-volume method, has been developed to describe mass diffusion velocities accurately. The new formulation is applied in a quasi-steady numerical model for n-heptane fuel droplet combustion in a forced-convection environment. Results obtained using the complete formulation are compared to the results obtained under various assum...
