Remarks
(specific information about assesment, entry requirements,
etc.): |
Goals:
The
student can:
-
understand, reproduce and apply the thermodynamic definitions in
relation to pumps
-
recognize and apply pump characteristics including their net positive
suction head behavior, parallel and series operation and capacity
control
-
understand, reproduce and apply the thermodynamic definitions in
relation to compressors including first and second law analysis and
multi-stage operation
-
identify thermodynamic losses that take place in compressors and to
explain how these losses are affected by the selected design
-
explain the working principles of positive displacement and dynamic
compressors
-
describe the basic construction of the different positive displacement
compressor types (including piston, helical screw, rolling piston,
rotary vane, scroll, roots-blowers and liquid ring compressors) and
their operation limits and capacity control capability
-
model, in a simplified way, the processes taking place in reciprocating
compressors taking piston displacement and (automatic) valve behavior
into account
-
quantify the effect of the built-in volume ratio on performance for the
relevant compressor types
-
recognize and apply characteristics of turbo machinery including their
operation limits and capacity control

Design
content:
This
course provides the students with engineering knowledge to size pumps and
compressors as part of a system. For reciprocating compressors a
simplified design model is discussed. |
Percentage of
design:
80%. |
