CHE4162 - Particle technology

Leader(s): K Hapgood

Offered

Clayton First semester 2009 (Day)
Clayton Second semester 2009 (Day)
Sunway Second semester 2009 (Day)

Synopsis

This unit provides a thorough introduction to particle technology. The unit begins with understanding particle characterisation, the fluid mechanics of single and multi-particle systems and particulate fluidization. The physics underlying powder flow will be covered to enable introductory hopper design. Common powder processing operations will be studied, selected from powder mixing/segregation, sedimentation, dewatering and size enlargement.

Objectives

After completing this unit, the student will be able to understand particle characterisation techniques and how the motion and fluid mechanics of a single particle and multi-particle assemblies are affected by particle properties. The student will be able to select a suitable particle characterisation method; manipulate particle size distribution data; model particle flow in fluids and fluidized beds; and be able to use particle properties to design a suitable powder hopper to ensure powder flow. Finally, the student will understand the underlying principles of several powder processing operations, be able to design the key parameters for that unit operation and develop an appreciation for the complexities of powder handling and processing.

Assessment

Laboratory reports: 15%, Assignments/tests: 15%
Final examination (3 hours): 70%
