Course detail

CFD in Heat Transfer Applications

FSI-LPT Acad. year: 2025/2026 Winter semester

Computational fluid mechanics provides a wide range of engineering applications. This course focuses exclusively on problems related to heat transfer. The goal of the course is to introduce students to the basic mechanisms of heat transfer and how they are implemented in CFD solver ANSYS Fluent. The course consists of a theoretical and a practical part. In the theoretical part, the student will get a deeper knowledge of the principles and models that lead to the correct solution of problems related to heat transfer within the computational domain. In the practical part of the course, students then solve problems related to heat transfer problems such as conduction, natural flow, radiation, heat exchangers, etc.. During the course, each student will choose an individual topic related to heat transfer problems for which he/she will be graded at the end.
