Description
Summary:Optimisation is essential in modern industrial and chemical process industries to increase efficiency and decrease downtime and maintenance costs. X-ray tomography is being developed to address these issues both on the microscopic level to characterise and quantify unit cell parameters and the macroscopic level for real time measurement of multiphase flow. The behaviour of macroscopic flow can be predicted using finite element simulations. Three-dimensional X-ray micro-tomography with 100 micron resolution has been developed and could be used to determine, for example volume fractions, contact surface area and particle size distribution and used as basic data for modelling of macroscopic systems. Additionally, a high speed X-ray tomography instrument is being developed to measure on-line multiphase flow in fast moving systems. This system does not require moving parts and is expected to operate at up to 50 frames per second. In addition to a practical implementation of this system in an industrial environment it can also be used as a cross-validation of the macroscopic models. Details of each system will be described and the suitability of the applications discussed.
