Recent research and development of combustion simulation

What we can express about the overall combustion phenomena is summerized by means of numerical simulation. Recent methods on numerical analysis of com bustion characteristics are studied for gas, liquid spray, and pulverized c oal fuel. Lagrangian and Eulerian approaches for the understanding of two p hase flow such as spray and pulverized coal combustion are then compared. Coal pyrolysis is also described by models based on the molecular structure . Not only a wall function model, but also low Re number model are applied for wall boundary treatment. The following submodels are furthermore shown; LES (Large Eddy Simulation) and k-epsilon two equation model, reduced comb ustion scheme for detailed reaction model, radiative heat transfer, soot fo rmation, NO production and drop breakup mechanism of liquid spray.
