Course detail

Modelling of Processes

FSI-IMPAcad. year: 2017/2018

In the course, students will get acquainted with basic types of mathematic models used for design, analysis and optimization of process systems and equipment.
• Model of processing line describing mass and energy balance of a continuous process
• Model of process equipment describing a batch process
• Model for the optimization of a process or equipment
• Model for detailed analysis of conditions inside of an equipment
Models included in the course are mostly based on a system of equations (mainly linear) and ordinary differential equations. Besides analytical solution of equations systems students will learn how to apply basic numerical methods to the solution of ODEs and to solve by graphical method linear optimization problems.

Learning outcomes of the course unit

Students will understand the basic principles of mathematical model design for complex systems. They will also learn about model application in practice. They will get an overview of process and energy systems and the types of models that are used for design, analysis and optimization. After finishing the course, students should be able to choose appropriate type of model for the design, analysis or optimization of a system or equipment, they should understand the basic principles of those models, have insight in corresponding solution methods and experience with their application.

Prerequisites

Process systems engineering, basic knowledge of mathematics, physics and thermomechanics from the first four semesters at FME.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures introducing the basic principles and theory, explaining of solution methods and showing solution methods. Lectures include sample problems that are solved interactively with the students, with emphasis on understanding. Lectures often include repetition of the most important prerequisites that are necessary to master the subject.

Seminars are focused on hands-on solution of sample problems complemented with work in software tools.

Assesment methods and criteria linked to learning outcomes

SEMINARS: Regular and active attendance is required and checked. Written test must be passed successfully. Test is successfully passed if more than half of points are obtained. The student has the possibility of one repeat.

EXAM: The exam is written. The course evaluation is performed by a standard procedure, according to the percent of obtained points (0-50%…F, 51-60%…E, 61-70%…D, 71-80%…C, 81-90%…B, 91-100%…A).

Aims

The objective is to acquaint students with the basic principles of mathematical models for design, analysis and optimization of industrial units (processes) or equipment. Students should be able to choose a proper model type for the solution of typical problems, understand the corresponding solution methods and be able to solve simple problems.

Specification of controlled education, way of implementation and compensation for absences

The attendance at lectures is recommended. The attendance at exercises is compulsory and checked.

Presence at lectures is necessary to understant solution methods, which are not explained at seminars, only practiced on example problems.
