Entry knowledge
Basic computational parts of elasticity and strength and parts of machines.
Rules for evaluation and completion of the course
Course-unit credit is conditional on participation in the seminars and submitting written reports of given computational processes.
Attendance at practicals is compulsory. Absence in justified cases has to be compensated for via a spacial task.
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).
Students will be able to create basic parts of fluid machines taking into account the stress analysis.
