湍流参数对燃烧过程有很大影响,而燃烧室中气体的流动常为三维湍流流动.三维湍流流场可采用激光测速仪进行测量,但必须在测量部位开设相应的窗口,因此测量范围要受到窗口的限制;而采用三维或二维热线风速仪测量时,不仅热线探头构造复杂,相应配置的仪器设备也较复杂,而且在探头安装上也有许多特殊要求,有时甚至是很难实现的. Turbulence parameters have a great influence on the combustion process, and the gas flow in the combustion chamber is often three-dimensional turbulent flow .Three-dimensional turbulent flow field can be measured by laser velocimetry, but the corresponding window must be opened at the measurement site, Window, and the use of three-dimensional or two-dimensional hot-wire anemometer measurement, not only the hotline probe structure is complicated, the corresponding configuration of the equipment is also more complex, but also in the probe installation has many special requirements, and sometimes even difficult to achieve.
