Analysis of experimental and numerical results of a turbulent swirling flow in a tube. Chemical Engineering Communications, 125(1), 187-196. Analysis of nitric oxide formation for turbulent swirling The present study is concerned with the effect of fuel droplet size, air inlet preheating and air swirl number on complex soot process in a turbulent liquid-fuelled combustor. Evaporating droplets in turbulence studied with Aug 31, 2018 · The present paper investigates droplet laden turbulent gas flows with point droplet direct numerical simulations. A novel flow configuration is presented, which allows us to simulate statistically stationary homogeneous isotropic regions of turbulent sprays.

Experimental and numerical study of separation

The separation characteristics of the gas-liquid cylindrical cyclone (GLCC) has been investigated by experiment and numerical analysis. The droplet size and phase distributions were measured using Malvern RTsizer and electrical resistivity tomography, respectively. The Discrete Phase Model was used to numerically analyze the swirling hydrodynamics.

Different turbulence models, that is, the v 2 f model, standard k model, and Reynolds stress model, were compared. PAPER OPEN ACCESS The effect of flow swirling on flow organized as follows. In Section 2, the governing equations and numerical method employed in this study for simulation of two-phase mist swirling flow are introduced. The numerical study of the droplet-laden swirling flow and results of comparative analysis is presented in Section 3. The last part summarizes the main findings and conclusions. 1.

Sheet, ligament and droplet formation in swirling primary

We report direct numerical simulations of swirling liquid atomization to understand the physical mechanism underlying the sheet breakup of a non-turbulent liquid swirling jet which lacks in-depth investigation. The volume-of-fluid (VOF) method coupled with adapted mesh refinement (AMR) technique in GERRIS code is employed in the present simulation.
