The subject is oriented to develop practical skills of students in the formulation of model equations of various chemical-engineering problems, their arrangement in the form suitable for the solution by equation-oriented program and acquirement of practical skills with simulations. Program MATLAB is selected as the basic tool for the modeling and alternative freely-available programs working with the same syntax of model equations are mentioned.

Students will acquire theoretical and practical skills for:

1. Writing of model equations for a broad class of chemical-engineering problems.

2. Processing of model equations by various methods, for example, by the finite volume method.

3. Arrangement of equations in the form suitable for equation-oriented simulators.

4. Simulation and vizualization of obtained results.
