Validation of Les Predictions for Turbulent Flow in a Confined Impinging Jet Reactor
This work focuses on the prediction of turbulent flow in a Confined Impinging Jet Reactor using Large Eddy Simulation (LES). Three dimensional transient simulations were performed for various flow rates, ranging from quasi-steady laminar flow to unsteady turbulent flow. Predictions of the mean and fluctuating velocities were compared with micro Particle Image Velocimetry (mPIV) data. Good agree...
متن کاملTurbulence in a microscale planar confined impinging-jets reactor.
Confined impinging-jets reactors (CIJR) offer many advantages for rapid chemical processing at the microscale in applications such as precipitation and the production of organic nanoparticles. It has been demonstrated that computational fluid dynamics (CFD) is a promising tool for "experiment-free" design and scale-up of such reactors. However, validation of the CFD model used for the microscal...
متن کاملHeat Transfer under Double Turbulent Pulsating Jets Impinging on a Flat Surface
In this study, the numerical analysis of turbulent flow and heat transfer of double pulsating impinging jets on a flat surface has been investigated. The unsteady two-dimensional numerical solution for two similar and dissimilar jets was performed using the RNG k-ε model. The results showed that the RNG k-ε model has more satisfactory predictions of the Nusselt number distribution. Comparisons ...
