The rapid evolution of the flow gives rise to a pair of bound vortices attached to the lee side of the jet boundary, to fast development of the turbulent and mean vorticity, to a vortex-shedding Author: Nicolas Lanitis. Here ANSYS Design Modeller is used for developing an open channel model having a cube of area 25 mm 2, which acts as an obstruction to the flow the midpoint of the right-hand side surface of the cube a jet orifice of diameter d = 10 mm is open channel flow having length of 18 m and width m is considered to initiate the : Manas Kumar Bhukta, Goutam Kumar Bose, Kaustav Debnath.

Goldschmidt Engineering Experiment Station School of Mechanical Engineering Purdue University Lafayette, Indiana Project No. DEP Program Element 1BA Project Officer George R. Ditsworth Pacific Northwest Environmental Research Laboratory . A Crossing Trajectory Simulation (CTS) model for turbulent two-phase flow is developed here to predict the response of solid particles to gas-phase turbulence in a two-phase turbulent round jet. The conservation equations are based on an Eulerian approach for the gas-phase; (k-ε model), and a stochastic approach for the particle-phase.

Round jets impinging at multiple impingement angles were considered for this study to gain better understanding of the parameters affecting resultant jet growth and velocity distribution. Work done by the authors previously on single jet has helped to establish that the SST (Shear Stress Transport) k-ω model is the ideal turbulence model for predicting flow characteristics of jets exiting a Author: Raj Narayan Gopalakrishnan, Peter J.

New features are found for the diffusion flame in a cross flow at the instability regime in the jet source. As for combustion in still air, the intermittent character of the torch formation is revealed. In the laminar flow phase (Figure 12 frame ), an extended section of the longer-range jet is observed.
