- First semester 2017 (Day)
This unit is available only to Engineering PhD students.
The unit will cover the purpose and methods of modelling chemical and biochemical processes. It includes the development of constitutive relations, model building, evaluation and sensitivity analysis. Numerical techniques will include the solution of systems of linear, non-linear and algebraic equations. Models are subjected to optimisation.
The basic principles of optimisation including the types of variables, linear and non-linear models, constraints and objective functions will be covered. Various optimisation algorithms for linear, non-linear problems and mixed integer problems are presented in the context of chemical process design. Multi-objective optimisation is used to explore trade-offs involved with sustainable process development.
On successful completion of this unit, students will be able to:
- build models of chemical and biological processes which respect conservation laws, apply suitable constraints and constitutive relations and choose an appropriate solution algorithm
- analyse complex models of chemical processes with an understanding of the mathematical structure of the model and the convergence methods used to obtain the model solution
- apply the appropriate optimisation strategy for linear, non-linear, unconstrained, constrained and mixed integer models from a fundamental understanding of functional and constraint convexity, or can choose the appropriate evolutionary solution strategy when convexity is not assured
- optimise both single objective and multi-objective process models to improve the process objective(s).
