Course outline
- (^) P process is a routine activity
- (^) M representation of a process as a real system
- (^) S interaction between process and model
Models
A model is the simplification of reality used to predict system behavior.
- (^) Physical Model
- (^) Mathematical Model Mathematical models can be useful in all phases of chemical engineering, from research and development to plant operations, and even in business and economic studies.
- (^) Research and development
- (^) Design
- (^) Plant operation:
Modeling and Simulation procedure
- (^) Translating the description of a physical system into an appropriate mathematical form.
- (^) Selecting a suitable computational technique.
- (^) Implementing the computational technique in the form of a computer program.
Simulation methodology
- Problem definition
- Design the study
- Design the conceptual model
- Formulate inputs, assumptions and process definitions
- Build, verify & validate the simulation model
- Conduct design of experiments
- Documentation
- Define the model life cycle
Limitations of simulation
o Lack of good data and knowledge of process mechanism. o Character of the computational tools o the danger of forgetting the assumptions mode in modeling the process
