Particle Measurement and Phase Doppler Technology

Module name (EN):
Name of module in study programme. It should be precise and clear.
Particle Measurement and Phase Doppler Technology
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Mechatronics, Master, ASPO 01.04.2020
Module code: MTM.PDT
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.
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.
2V (2 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: according to optional course list
Mandatory course: no
Language of instruction:
Term paper

[updated 01.10.2020]
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

MTM.PDT (P231-0111) Mechatronics, Master, ASPO 01.04.2020 , optional course, technical
MST.PDT (P231-0111) Mechatronics and Sensor Technology, Master, ASPO 01.04.2016 , optional course, technical
MST.PDT (P231-0111) Mechatronics and Sensor Technology, Master, ASPO 01.10.2011 , optional course, technical

Suitable for exchange students (learning agreement)
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).
30 class hours (= 22.5 clock hours) over a 15-week period.
The total student study time is 90 hours (equivalent to 3 ECTS credits).
There are therefore 67.5 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
MTM.LKO Laser Measurement Technology and Design Methodologies

Recommended as prerequisite for:
Module coordinator:
Prof. Dr. Martin Löffler-Mang
Lecturer: Prof. Dr. Martin Löffler-Mang

Learning outcomes:
In this course, students will deepen their knowledge of particle measurement technology (Based on the "Lasermesstechnik" course), especially Laser Doppler Particle Analysis (PDPA). After successfully completing this course, students will thus have mastered the statistics of particle size distributions, the theoretical basics of PDPA and know how to handle a modern PDPA system. They will be able to independently measure and interpret a nozzle spray with PDPA.
