Characterization of airflows at the exit of registers using Laser Doppler Velocimetry (LDV).

Author(s) : TUTU N. K., KRISHNA C. R., BUTCHER T. A.

Summary

This paper reports the results of fluid flow measurements carried out at the exit of sidewall registers. These data can then be used as an input boundary condition in a computational fluid dynamics (CFD) code to predict the velocity and temperature distribution in an enclosure supplied by the registers. LDV was used to measure the axial and vertical components of the velocity vector at various locations across the face of the registers. Measurements at distances removed from the exit plane of the registers, but still within the "near field," show how the complex profile due to the vanes transitions to a jet, and this can provide a partial validation measurement for the CFD results.
