Course Description

Time–varying operation of chemical and biochemical processes is introduced. Dynamic mathematical models are formulated using material and energy balances. Effects of operational and design parameters on steady-state and dynamic operations are investigated. Numerical techniques are introduced to solve systems of algebraic and differential equations. Numerical and symbolic computation tools are used to analyze dynamic and steady-state process behaviour. (22/0/0/20/0)

Objectives and Outcomes

This course introduces basics of mathematical modeling and numerical methods for systematic analysis of transient and steady states of chemical processes.

Specific course learning outcomes (CLOs) are:

  1. Develop dynamic and steady-state models of chemical processes using mass balance, energy balance and constitutive relationships.
  2. Calculate states, inputs or parameters at steady states via solving relevant algebraic equations.
  3. Analyze process dynamics via solving relevant ordinary differential equations.
  4. Develop linearized models with deviation variables, and assess the stability of process steady states via both eigenvalue analysis and Laplace transform of the linearized models.
  5. Solve complex algebraic and ordinary differential equations using MATLAB built-in functions, and implement classical numerical methods on MATLAB.
