Falling liquid film characterization in the inside wall of vertical tube using whirl feeder through experiment and CFD simulationFalling Liquid Film (FLF) from swirl feed holes were characterized through experiment and Computational Fluid Dynamic (CFD) simulation. The falling liquid film is quantified by its thickness. The effect of liquid flow rate, physical properties and diameter of swirl holes are successfully correlated to form a model that is based on the liquid film theory. The FLF dimensionless thickness linearly relates to power functions of Reynolds and Galilea numbers. The minimum m

Abstract:
In order to address the impact of the concentration gradients on the chemistry – turbulence interaction in turbulent flames, the REDIM reduced chemistry is constructed incorporating the scalar dissipation rate, which is a key quantity describing the turbulent mixing process. This is achieved by providing a variable gradient estimate in the REDIM evolution equation. In such case, the REDIM reduced chemistry is tabulated as a function of the reduced coordinates and the scalar dissipation rate as an additional progress variable. The constructed REDIM is based on a detailed transport model includi

Abstract:
A hybrid RANS/Transported-PDF model for the simulation of turbulent reacting flows based on automatically reduced mechanisms for the chemical kinetics (reaction-diffusion manifold, REDIM) is presented in this work. For modelling of turbulent reacting flows, chemistry is a key problem and affects largely the accuracy. The PDF method has been widely used since the chemical source term is in a closed form, without any modelling. Despite of this advantage of PDF method, detailed chemical kinetics is not desired due to its heavy computational effort. From this aspect, the detailed chemical kinetics

Abstract:
The characteristics of partially-premixed flames is investigated by simulating a series of triple flames with different variations of chemical equivalent ratio. A two-dimensional Reaction-Diffusion Manifold (REDIM) chemistry tabulation method is employed in the simulation and the results are compared with the methane-air 19-step chemical reaction mechanism. The performance of these two mechanisms is then assessed by using direct numerical simulations coupled with GRI3.0 detailed mechanism. It is shown that both 2D REDIM table and 19-step simplified mechanism can describe the temperature and ma
