Study on the coupling mechanism and suppression characteristics of swirl premixing combustion self-excited oscillation

Case Studies in Thermal Engineering
The numerical simulation method was used to study the mutual influence of flow field disturbance, vortex change, flame structure change, heat release pulsation, and pressure pulsation on the coupling mechanism and suppression characteristics of self ...

Design and preliminary experiment of a 0.3 × 0.15 m2 low-disturbance supersonic wind tunnel [PDF]

AIP Advances
To meet the requirement for the low disturbance of wind tunnel flow in supersonic boundary layer transition simulation tests, a low-disturbance supersonic research wind tunnel with a nozzle size of 0.3 × 0.15 m2 and test Mach number of 3.0 was built.

Laboratory modeling of flow regimes in a draft tube of Francis hydro-turbine

EPJ Web of Conferences, 2017
The paper reports on some results of the experimental study of flow and pressure pulsations in a laboratory model of the draft tube (DT) of Francis-99 hydro-turbine over a broad range of operating regimes. Velocity distributions at the model inlet varied

Effects of cutting the blade on the performance and pressure pulsation of a centrifugal pump

Energy Science & Engineering, 2020
To solve the severe flow‐induced vibration during the pump operation, the impeller cut is a reasonable and operable approach. In the present study, effects of cutting the blade on the pump performance, especially for pressure pulsations, are conducted by
