Dynamic Roller Compactor

…it becomes possible to design, optimize, and control the process based on the model.The simulator was built using Matlab. The user can vary three input variables: roll pressure, feed speed and roll speed. They can be specified as a function of time. For example, if the roll pressure is assigned as 1*step(t-3), the simulator increases the roll pressure from 1MPa to 2MPa at t = 3 min. All Matlab functions are supported for specifying the patterns of the input variables. Dynamic simulation of roller compaction for dry granulation Launch Tool

High Shear Mixer

Granular mixing remains an art rather than a science and is a hot research topic in adademia as well as in industry. Granular materials display wide range of behaviour ranging from poor mixing to segregation based on mixer characteristics and operating regimes. Understanding how the materials in the… Launch Tool

Roller Compactor

The impact of material properties and process parameters are determined using a continuum model. Normal stresses for roller compaction are calculated from Johanson's rolling theory. The boundary between the slip and nip regions is calculated using Johanson's criterion, i.e. gradients of stress in sl… Launch Tool

Analysis of Cake Filtration

Filtration models can be used to analyze and optimize filtration operations. A cake filtration equation, which describes the variation in filtration flow rate as a function of operating parameters and physical properties, can be derived by applying Darcy’s law to the filter cake and medium [Rushton … Launch Tool

Extending the square root method to account for model noise in the ensemble Kalman filter

Presented by Patrick Raanes on 2-18-2015 Abstract:A novel approach to account for model noise in the forecast step of the Ensemble Kalman filter (EnKF) is proposed. The core method is based on the approach of the analysis step of ensemble square root filters (ETKF), and consists in right-multiplying…
