    • A method and apparatus to simulate a flow of products from a real fire without reproducing a thermal environment associated with the real fire includes the release of a gas or a mixture of gases with an appropriate density less than air to simulate smoke movement from real fire sources. The buoyant inert gas may be helium. In some embodiments, the buoyant gas is combined with artificial smoke, such as a tracer gas or an inert dye (e.g., a particulate) to provide a visual representation of the location and flow characteristics of the surrogate smoke that is released from a release apparatus. In another embodiment, optical techniques that show differences in gas density are used to visualize the movement of the buoyant gas. The release apparatus includes a control system that follows a prescribed time-dependent flow rate to simulate different fire source configurations and growth rates.
    • 用于模拟来自真实火灾的产品流动而不再现与真实火灾相关联的热环境的方法和装置包括释放具有比空气小的适当密度的气体或气体混合物以模拟来自真实火源的烟雾运动 。 漂浮的惰性气体可以是氦气。 在一些实施例中,浮力气体与诸如示踪气体或惰性染料(例如,颗粒)的人造烟雾结合,以提供从释放装置释放的替代烟雾的位置和流动特性的视觉表示 。 在另一个实施例中,使用显示气体密度差异的光学技术可视化浮力气体的运动。 释放装置包括遵循规定的时间依赖流量以模拟不同的火源配置和生长速率的控制系统。

    • A method and apparatus for reducing total pressure loss in the exhaust of a combustion device via an axial diffuser having no turning vanes, support struts, rods, or other obstructions to exhaust flow. The axial diffuser includes an inner wall and an outer wall each having a turn radius and forming an annular cross section having increasing cross-sectional area in the downstream direction of flow, the flow being transitioned from axial to radial direction thereby. The diffuser is supported in the plenum by rods, struts or a cradle; from a stand surrounding the axial diffuser via struts or rods; or from existing diffuser support structure by web stiffeners. The diffuser flow path turn radius of the outer wall ranges from about 50-95% of the radial distance from the inner wall to a wall of the exhaust plenum, and of the inner wall ranges from about 10-70% of this distance.
    • 一种用于通过轴向扩散器减少燃烧装置的排气中的总压力损失的方法和装置,所述轴向扩散器没有转动叶片,支撑支柱,杆或其它阻碍物排出流动。 轴向扩散器包括内壁和外壁,每个外壁具有转弯半径并且形成具有在下游流动方向上具有增加的横截面面积的环形横截面,该流动从轴向向径向过渡。 扩散器通过杆,支柱或支架支撑在增压室中; 通过支柱或杆从围绕轴向扩散器的支架上; 或通过腹板加强件从现有的扩散器支撑结构。 外壁的扩散器流路转弯半径在从内壁到排气室的壁的径向距离的约50-95%的范围内,并且内壁的范围为该距离的约10-70%。
