| THE 3DIMENSIONAL (TRIAXIAL) INDICATOR FOR A BULK SOLID PRESSURE OBSERVATION IN A SILO |
Abstract
Yet, there are not investigated means able to register real stresses/pressures inside storage systems properly. Current indicators work in 2D generally and moreover, usually are situated to inner circumference of a silo body. That is the reason, why often a wall stress/pressure has been measured instead of a real stress/pressure inside bulk solids pored in a silo. The problem is more acute in regard to transport of tough flow powder, which often changes flow properties depending upon storage and environmental conditions, such as storage time, temperature, moisture, etc. Detection of the real pressure inside the storage mass using the stress/pressure indicator may be a possible solution of the problem, which is encouraged by modelling of the particulate solid flow.
The paper deals with a bulk solid pressure observation inside a silo using new developed 3Dimensional (Triaxial) Indicator. New design and conception of the 3D indicator have been developed exclusively for detecting of real stresses/pressures inside vessels, bunkers and silos. Real results and outputs of the investigation will be presented and discovered in the paper.
