引言燃气轮机燃烧室经常采用离心式喷油咀。长期以来,这种型式的喷油咀是根据理想流体的“离心式喷咀理论”进行设计的。由于理想流体的理论忽视了燃油实际具有的粘性,又不考虑燃油流经喷咀时发生的能量损失即油压损失,因而流量系数和喷雾锥角的设计值和实测值之间出现很大的偏差。范作民和张洪才在“离心式喷咀的理论与计算”一文中,提出了实际流体的理论,即考虑了燃油的粘性,又计入了能量损失,从
Introduction Gas turbine combustors are often used with centrifugal injectors. This type of nozzle has long been designed according to the “Centrifugal Jet Theory” of the ideal fluid. Since the ideal fluid theory ignores the actual stickiness of the fuel and does not take into account the energy loss that occurs when the fuel flows through the nozzle, that is, the hydraulic pressure loss, the design and measured values of the flow coefficient and the spray cone angle are large deviation. Fan Zuomin and Zhang Hongcai in the “theory and calculation of centrifugal nozzle,” a paper, put forward the theory of actual fluid, that is, taking into account the viscosity of the fuel, but also included in the energy loss, from
