Design of Nozzle for UV Fluorescence Detector

Abstract

The flow through the nozzle of a Ultra-Violet (UV) Fluorescence detector is computed. The primary goal of this project is to study the flow exiting the nozzle and predict the spreading of the flow at a specified distance from the exit of the nozzle. The unstructured mesh-based incompressible flow solver, FEFLO, is used to compute this flow. Computed pressure drops across the nozzle are compared with experiment and shows good agreement. Several computations are performed varying the flow rates through the nozzle and the position of the inner capillary tube with respect to the exit of the nozzle. The effect of these parametric variations on the spreading rate of the flow is studied. This will serve to design the nozzle configuration and optimum flow condition.
