Abstract
In response to the stringent requirements of methanol delivery for flow stability and sealing reliability, this paper focuses on the cycloidal rotor methanol pump, conducting multi-objective optimization design and performance analysis. By improving the trochoid curve design of the inner rotor teeth and using the envelope method for outer rotor adaptation design, key structural parameters are determined and the fuel supply calculation formula is derived. With the aid of UG, SolidWorks, and ANSYS ICEM CFD, three-dimensional and fluid domain models are constructed. Flow field simulation is conducted based on the Navier-Stokes equations and the standard k-ε model to analyze velocity, pressure, and flow pulsation characteristics. The results show that during stable pump operation, the flow pulsation rate is reduced to 6.6%, there is no severe negative pressure in the trapped oil zone, and the methanol engine fuel supply requirements are met. This research provides theoretical and technical support for the performance improvement and engineering application of cycloidal rotor methanol pumps.
As a critical regulating component in subsea Christmas tree systems, the cage-type choke valve governs the overall production efficiency and operational reliability of offshore oil and gas exploitation owing to its unique internal flow field characteristics. In accordance with the in situ operating conditions of the ta...

Supersonic ejectors are widely used in refrigeration systems due to their potential to improve system performance. However, their performance is highly sensitive to geometric parameters, requiring both a comprehensive understanding of internal flow behavior and systematic investigation. In this study, a CFD model valid...
