Abstract: A method for predicting flow properties of one or more materials proposed for processing in a system that requires good flow properties to operate successfully includes identifying a plurality of key flow points along a system, for each key flow point so identified, characterizing the type of flow occurring at that key flow point, for each key flow point, selecting a flow test relevant for modeling the type of flow occurring at that key flow point, providing a plurality of material samples wherein each material sample has a different composition, blend and/or concentration of ingredients, for each key flow point, modeling the type of flow occuring at that key flow point by conducting the flow test selected for that key flow point on each material sample to produce a plurality of test result values, wherein each test result value is a function of one of the flow tests conducted and of the material sample tested by that flow test, and ranking each material sample based on a calculated average of the test result

Abstract: A method for predicting flow properties of a material such as a pharmaceutical powder, which material is proposed for processing in a system that requires good flow properties for its successful operation. The method includes identifying key flow points along the system and, for each key flow point so identified, characterizing the type of flow occurring at that key flow point and selecting a flow test relevant for modeling the type of flow occurring at that key flow point. A plurality of material samples are selected as being candidates for processing in the system, wherein each material sample has a different composition, blend or concentration of ingredients. For each key flow point and for each material sample, the flow type characterizing the key flow point is modeled by conducting the specific flow test selected for that key flow point.
