Numerical study of a confined slot impinging jet with nanofluids

BACKGROUND Heat transfer enhancement technology concerns with the aim of developing more efficient systems to satisfy the increasing demands of many applications in the fields of automotive, aerospace, electronic and process industry. A solution for obtaining efficient cooling systems is represented by the use of confined or unconfined impinging jets. Moreover, the possibility of increasing the...

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...
