Abstract
A process for mitigating shear induced particle migration of highly filled explosive suspensions during injection loading of the explosive suspension into a confined container that includes monitoring particle migration within the highly filled explosive suspension and correcting flow parameters effective to reduce the particle migration.
Claims12
A process for mitigating shear induced particle migration of explosive suspensions during injection loading of the explosive suspension into a container, comprising:
- monitoring said process for initiating performance of a corrective process control for minimizing particle migration within the explosive suspension;
- and,
- correcting flow parameters effective for reducing the particle migration,
- wherein said monitoring comprises using a neural network framework, which includes a plurality of input nodes and a plurality of hidden nodes, for real-time monitoring of process parameters to initiate said corrective process control,
- wherein said corrective process control comprises process diagnostics and process control requirements are accommodated to fill different munitions with said explosive suspension through use of a densitometer,
- wherein said correcting flow parameters is a corrective action for a non-steady state process invoked within one time step to resolve an influence of a disturbance before an injection loading cycle is complete, and
- wherein said correcting flow comprises shear is re-distributed in said explosive suspension, and density and concentration gradients are prevented in said different munitions when filled through use of in-line static mixers.
