Phosphorescent sands for hydraulic and fluid mechanics tests

Method of Identification under ultraviolet lamp

USAGE

The phosphorescent sands developed by the SNL are intended for identification under ultraviolet lamp

They are specially designed to be useable in pond water or river water and remain phosphorescent for several years. The sands were tested in an independent laboratory to ensure the innocuity of the sands while used in water, without consequences for aquatic environments.

The most common uses are:

• Monitoring of the consequences of floods and dam releases in rivers: this method was developed by researchers from Electricité de France to identify the presence of sand deposited upstream in samples taken at different distances and times

• Hydraulic study in a basin
• Avalanche studies

The use of phosphorescent sand can allow the use of photos, videos and AI to track movements in fluid mechanics, facilitate modelling or confirm mathematical models.

TECHNICAL CHARACTERISTICS

The sand is of the natural siliceous type with a water content of less than 0.1%. The constituent grains of these sands are uncrushed and round-shaped. It has a silica content of more than 98%.

CONTROLES

The sand is controlled under a UV lamp

DELIVERY

The sand is packaged on demand either in small or big bags to facilitate its transport and use in various environments.
