Description

The module Fluid Machinery offers beside a comprehensive overview over different types of fluid machinery the theory and the necessary defintions in order to characterize fluid machinery. In detail it covers:

properties and area of application of fluid machinery.

Introduction and discussion of characteristic fluid machinery types: centrifugal pump, water turbines, wind turbines, gasturbines, turbo charges.

Thermo- and fluiddynamic fundamentals: basic equations, analogy principles and characteristic properties.

Blade row aerodynamics: fluid flow kinematic, one-dimensional calculations methods.

Performance: characteristic and performance map.

Fundamentals of fluid machinery design.

Learning outcome

At the end of the module students will be able

- to understand the fundamental thermo- and fluiddynamic behavior of fluid machinery,

- to give detailed descriptions of the main elements and applications of fluid machinery and

- to understand the basic blade row aerodynamics and their influence on the machinery operating conditions.

With this qualification the students are capable of estimating the performance of a fluid machinery and their influence on the overall energy system.

Media

A scripted version of the slides of the interactive presentation that accompanies the lecture will be handed out.

Teaching and studying methods

90 min. lecture with time for students to ask questions.

45 min. exercise will help to solidify lecture knowledge by learning from worked-out-examples.

Autonomous preparing at home is needed to fulldy understand the learning matter.
