SYSTEM AND METHOD FOR SPRAY VISUALIZATION

[Category : - Automotive Accessories - Construction Processes & Equipment- Agriculture]
[Viewed 369 times]

A spray visualization apparatus and method are disclosed. Unlike laser or Doppler techniques requiring costly instrumentation, the herein disclosed technique is much simpler. The apparatus comprises a hollow flow tube, an injector device coupled to the hollow flow tube, and at least one membrane surface material substantially positioned cross-flow in the hollow flow tube. The method relies on a fluorescent dye marking the spray droplets impinging on the membrane surface material. The image of spray droplets on the membrane reveals the distribution pattern of droplets in the oncoming flow as the droplets impinge on the membrane. A digital scan of the membrane is acquired. The scanned image is quantitatively analyzed for droplet size, amount and uniformity index. The disclosed technique is a low-cost alternative for study and testing spray patterns generated by automobile emissions.
