doc. Ing. Vojtěch Turek, Ph.D.

Institute of Process Engineering

• The fundamentals of mathematical analysis, linear algebra and numerical methods at the Bachelor’s level,
• The basic concepts of fluid mechanics and thermomechanics (conservation laws, laminar and turbulent flow, heat and mass transfer),
• Ability to work with common engineering software in the Windows environment and to work independently in a computer lab,
• Ability to study professional texts in English (ANSYS documentation and tutorials).

The course is completed with a course-unit credit (pass/fail); no examination or graded course-unit credit is awarded.

Ongoing monitoring of the study is carried out by checking students’ independent work on the tasks directly in the exercises and by reviewing the partial steps of the semester project solution.

The controlled instruction comprises all computer-assisted exercises. Missed classes shall be made up through individual study of the respective topic according to the teacher’s instructions; making up missed classes is a condition for awarding the course-unit credit.

The resulting classification of the course is two-level: course-unit credit (passed) / no credit (failed). The credit is awarded after meeting the active-participation condition and successfully completing the project.

The objective of the course is to acquaint the students with the fundamentals, applications, advantages, disadvantages, and potential pitfalls of Computational Fluid Dynamics (CFD). The students will master the basics of workflow using professional CFD tools within the ANSYS environment; however, the acquired knowledge also applies to other CFD packages. The students will be self-sufficient in solving and analysing fundamental fluid flow problems. The subject also provides a way to relate and deepen theoretical knowledge from other essential process engineering disciplines, which are taught in other courses.

The acquired theoretical and practical knowledge can be further developed in the specialised follow-up course “Practical applications of CFD (K20)”, which will prepare students to utilise CFD in engineering practice.

Study materials are available in the e-learning course for the KPT course (BUT Moodle) for the respective academic year:

• presentations covering the theoretical foundations of CFD
• exercise presentations (tutorials with assignments, task analyses, workflows, and results analysis)
• exercise resources in the form of executable scripts, Excel spreadsheets, and geometry and mesh files for selected tasks
• textbooks written in Czech
• supplementary exercises and suggestions for further work
• links to relevant websites and YouTube channels dedicated to CFD topics
• An automatically evaluated CFD quiz with feedback on the answers to verify students' own understanding of the subject matter.
