旋涡燃烧室气固流动特性冷态试验研究

Experimental Study on Gas-Solid Flow Behavior in Cold Model of Vortex Combustor (VC)

分别在探索性、实验室规模和全尺寸旋涡烯烧室冷态试验模型上进行了气固流动特性试验研究。介绍了颗粒相密度和质量流率、气固滑移速度、颗粒尺寸分布、颗粒停留时间分布和颗粒被气流“夹带”的规律的试验结果,并讨论了某些结构和操作参数对气固流动特性的影响。

Experimental tests of gas-solid flow behavior were conducted on exploratory, bench-scale and full-scale VC cold model, respectively. The test results of particle phase density and mass flux,gas-solid slip velocity, particle size distribution, resident time distribution of particles and particle entrainment were introduced, and influences of some configurational and operational parameters on gas-solid flow behavior in VC cold model were discussed.
