CP515 Modelling and Simulation of Simultaneous Transport Phenomena with MATLAB® and COMSOL Multiphysics® (3 credits)

Pre-requisite: Prior exposure to mathematical modelling using momentum, energy and mass transport phenomena; EM203 Numerical Methods in Chemical & Process Engineering or equivalent

Aim: Chemical & process engineering undergraduates at University of Peradeniya learn the foundations in process modeling in independent course modules dealing with momentum, energy and mass transport phenomena. Successful application of what are learnt in the said independent course modules to deal with practical process engineering systems require the following skills in an undergraduate

  1. Modelling of practical process engineering systems in a unified framework where momentum, energy and mass transport phenomena often occur simultaneously.
  2. Simulation of such complex systems modelled in a unified framework using advanced simulation packages such as MATLAB® and COMSOL Multiphysics®.

The proposed course module is designed to impart the aforementioned skills in the chemical and process engineering undergraduates.
Intended Learning Outcomes (ILOs):

  • Derive mathematical models of practical process engineering systems in a unified framework where momentum, energy and mass transport phenomena occur simultaneously, supplemented by empirical relationships, where necessary
  • Simulate published case studies where the coupling between different mathematical models is implemented using MATLAB® and COMSOL Multiphysics®
  • Critically analyze the simulation results by carrying out error analysis, sensitivity analysis and uncertainty analysis and by benchmarking the solution
