An Analytical Model for Flame Propagation through Moist Lycopodium Particles with Non-unity Lewis Number

In this investigation, the structure of one-dimensional flame propagation in uniform cloud of volatile organic particles has been analyzed in which the structure of flame is divided into three zones. The first zone is preheat zone which is divided into three subzones itself. In first subzone (heating), particle cloud heated until the moisty particles reach to vapor vaporization temperature. In ...

one-dimensional numerical model of cohesive sediment transport in open channel flow

cohesive sediment transport remains a complicated subject that hydraulic engineers are frequently faced with in water-related engineering problems. this is primarily affected by the macroscopic aspects of water-sediment system characteristics. in this paper a 1-d mathematical model was developed to be employed in predicting the cohesive sediment transport under simultaneous conditions of erosio...

Large eddy simulation of stably stratified open channel flow

a 2d numerical depth-averaged model for unsteady flow in open channel bends

the purpose of this paper is to present a 2d depth-averaged model for simulating and examining unsteady flow patterns in open channel bends. in particular, this paper proposes a 2d depth-averaged model that takes into account the influence of the secondary flow phenomenon through calculation of the dispersion stresses. the dispersion terms which arose from the integration of the product of the ...
