This course offers an introduction to CONVERGE for modeling flows in compressors and pumps. Although compressors and pumps can differ greatly from one another in terms of geometry and motion types, all compressor and pump simulations benefit from CONVERGE’s autonomous meshing capabilities. You will see how many of the same concepts can be applied to a variety of geometries and motions typical of compressors and pumps.
The majority of the course will focus on positive-displacement devices such as reciprocating, gear, scroll, or vane compressors and pumps. A smaller section will be devoted to dynamic machines such as centrifugal and axial compressors and pumps. For hands-on practice and demonstrations, the course will reference example cases drawn from the following list:
R-134a reciprocating compressor
Large bore gas processing compressor
Roots blower
Dry claw vacuum pump
Dry air screw compressor
Oil flooded screw compressor
Supercritical CO2 scroll compressor
Rotary vane compressor
Diesel fuel piston pump
Gerotor oil pump
Pendulum-slider oil pump
Axial compressor periodic sector
Turbocharger centrifugal compressor
Centrifugal coolant pump
After this course is completed, you will be able to:
Define appropriate fluid properties for gases and liquids
Set up boundary motion prescriptions for
reciprocating pistons
counter-rotating screws and gears
orbiting scrolls
sliding vanes
Set up fluid-structure interaction models for pressure-relief valves, plate valves, and reed valves
Address leakage flows through gap sealing, gap flow resolution, and gap flow modeling
Incorporate multiphase effects into the models, including:
Oil flooding and gas condensation in compressors
Compressibility, aeration, and cavitation effects in pumps
Determine grid controls and time controls for resolving valve opening events and pressure fluctuations
Set up initialization strategies for efficiently reaching statistically stationary states
Apply the multiple reference frame (MRF) approach to rotating components
*This lecture includes hands-on CONVERGE Studio practice.
