Multiple Jets Interaction

A scaled, separate effect facility was built to model the upper plenum of the Reactor Core Cavity Cooling System (RCCS).  

Project Description

scaled effect facility equipped with Particle Image Velocimetry (PIV)
scaled effect facility equipped with Particle Image Velocimetry (PIV)

The setup allows to investigate the interaction of up to 6 rectangular jets. The facility is equipped with Particle Image Velocimetry (PIV) for high-resolution measurements of the velocity field.

Examples of PIV measurements for 2, 4 and 6 interacting jets are shown in the videos below together with the corresponding averaged axial velocities.
