Dr Ali Hassanpour

Responsibilities

• Programme Manager, MEng, BEng Chemical Engineering; MEng, BEng Chemical and Energy Engineering;
• Leader of Complex Systems and Processes Research Group

Research interests

• Distinct Element Method (DEM) and coupling with Computational Fluid Dynamics (CFD) simulation of the granular media in order to relate bulk behaviour to single particle properties
• Mechanical characterisation of particles: Measurement of hardness, Young's modulus, yield stress, fracture toughness, size, density and porosity
• Size reduction: Breakage and attrition of the particles (during milling, impact, bulk compression, shear deformation and fluidisation) and study of its relationship with single particle properties
• Compression behaviour of the bulk particles (in terms of deformation, compaction, crushing) and its relationship with single particle properties
• Flowability of powders: Measurement of flow factor by annular shear cell and unconfined yield stress and establishing its relationship with single particle properties
• Size enlargement: Granulation of powders, including wet granulation in high shear mixers, modelling and scale-up of high shear mixer granulators
• Dispersion of powders: For the application of dry system size analysis, and dry powder inhaler
• Electrostatics effects on powders: Tribo-electrification of pharmaceutical powders, segregation of formulated bulk powders due to electrostatic effects
• Deformation, break-up and coalescence behaviour of drops under electric field
