This study employs the high-speed shadowing technique to examine near-field trajectory and penetration characteristics of water jets in a crossflow with different velocity gradients, which is achieved by multislot plate version same channel located 100 mm upstream nozzle. The findings reveal that, under identical average incoming velocities but gradient along jet direction crossflow, breakup mode changes due variable aerodynamic pressures exerted on interface; when from positive negative,...
The pilot flame’s effects on dynamic stability have been investigated in a bluff-body stabilized combustor at atmospheric pressure. During the experiment, fuel proportion increased from 6 to 20% with an interval of 2%, while total equivalence ratio remained unchanged. Simultaneous pressure and unsteady heat release rate measurement analysis were used identify characterize combustion instability modes. Combustion dynamics captured by high-speed camera. High-speed images further analyzed using...
Solenoid coil is a very important structure in micro-electronic filed. In this paper, we for the first time present method that can fabricate solenoid by casting. The named micro-casting like macro-scale casting, however micro-scale liquid phenomena introduced as gating system to overcome high surface-tension. Together with silicon bulk micromachining, integrated coils be fabricated batch and on single-stage forming method. Therefore, addition wire-bonding electroplating, provide an...
Sudden extinction of a microturbojet engine combustor was encountered during the accelerating process, which motivates present work to optimize performance. Numerical results show that by decreasing primary zone air-introducing area and increasing dilution area, air percentage is reduced from 39.35% 32%, excess ratio 1.122 0.915, believed be beneficial for flame stability both in terms residence time rich burn. Meanwhile, vortex flow pattern varies little as variations airflow distribution....
The characteristics of the flow fields in a model combustor’s primary zone, which is confined by different swirl cups and flame tube with holes cooling air films, experimentally investigated Particle Dynamic Analyzer (PDA). spray RP-3 jet fuel from atomizer used as trace particles for laser detection. inlet pressure temperature are 110 KPa 300 K, respectively. test sections start 10 mm end at 50 downstream cup, ensuring that located within range. results show cup double radial swirlers...
