Learning outcomes of the course unit
Students will be able to create basic parts of fluid machines taking into account the stress analysis.
Prerequisites
Basic computational parts of elasticity and strength and parts of machines.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
Course-unit credit is conditional on participation in the seminars and submitting written reports of given computational processes.
Aims
The aim of the course is to familiarise students with basic stress analysis of fluid machines, designed according to the given parameters (especially runner and spiral case), and the proposal of basic parts (shaft, bearings).
Specification of controlled education, way of implementation and compensation for absences
Attendance at practicals is compulsory. Absence in justified cases has to be compensated for via a spacial task.
