Fluid Mchanics

Module name (EN):
Name of module in study programme. It should be precise and clear.
Fluid Mchanics
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Mechanical Engineering, Bachelor, ASPO 01.10.2023
Module code: DFBME-409
The exam administration creates a SAP-Submodule-No for every exam type in every module. The SAP-Submodule-No is equal for the same module in different study programs.
P610-0329, P610-0344, P610-0548
Hours per semester week / Teaching method:
The count of hours per week is a combination of lecture (V for German Vorlesung), exercise (U for Übung), practice (P) oder project (PA). For example a course of the form 2V+2U has 2 hours of lecture and 2 hours of exercise per week.
4VU (4 hours per week)
ECTS credits:
European Credit Transfer System. Points for successful completion of a course. Each ECTS point represents a workload of 30 hours.
Semester: 4
Mandatory course: yes
Language of instruction:

[still undocumented]
Applicability / Curricular relevance:

DFBME-409 (P610-0329, P610-0344, P610-0548) Mechanical Engineering, Bachelor, ASPO 01.10.2019 , semester 4, mandatory course
DFBME-409 (P610-0329, P610-0344, P610-0548) Mechanical Engineering, Bachelor, ASPO 01.10.2023 , semester 4, mandatory course
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
Recommended as prerequisite for:
Module coordinator:
Prof. Dr. Marco Günther
Lecturer: Prof. Dr. Marco Günther

Learning outcomes:
After successfully completing this module, students will be familiar with the basics of fluid mechanical quantities and laws. They will be able to apply the laws of fluid mechanics to simple practical problems from the fields of hydrostatics, hydrodynamics and aerodynamics. Students will be able to perform calculations of state variables in incompressible and compressible flows and have basic experience in using a calculation tool. Exercises will teach students to classify fluid statics and steady-state fluid mechanical processes and their effects, taking into account the factors that influence them, and to calculate them in engineering terms.
