    This research adopts a shock tube 16 meters long and with a 9 cm bore to create a supersonic, high-temperature, and high-pressure flowfield to observe the gasification and ignition of HTPB solid fuel under different environments. Also, full-scale 3D numerical simulation is executed to enhance the comprehension of this complex phenomenon. The CFD (Computational Fluid Dynamics) code is Cited by: 2. 4 1 where ∆P is the pressure drop (Pa), L is the depth of the bed (m), V is superficial or frontal air velocity (m s-1).Constants a 2 2 and b 2 are tabulated in ASAE D [8]. The specified airflow 3 range for alfalfa pellets is to m s 4 Ray et al. [10] investigated air flow versus pressure drop characteristics for feed pellets 5 mm, mm, and mm in diameter as.

    High speed digital images were recorded with a Phantom V camera at a frame rate of Hz that was synchronized with the simultaneous pressure measurements. A realistic aviation gas turbine fuel injector was used to atomize the liquid Jet-A fuel. This injector is very.   Solids have a fixed shape and occupy a fixed volume. Liquids, because they flow, can occupy whatever shape their container has, so they do not have a fixed shape. Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed. Gases can also flow, so occupy the shape of their whole container. Matter is defined as anything which has volume and mass. Three phases of matter: Solid, liquid and gas. Solid: The substances in which particles are closely packed, has definite volume and definite shape. Liquid: Particles are loosely packed as comparison to solid, has definite volume and take the shape of container i.e. indefinite shape.

    This work studies the turbulent flame structure, the reaction-zone structure and the exhaust emissions of strongly-pulsed, non-premixed flames with co-flow swirl. The fuel injection is controlled by strongly-pulsing the fuel flow by a fast-response solenoid valve such that the fuel Cited by: 1. A solid has a defined shape and volume. A lump of metal will stay the same shape and volume unless or until you apply heat. Heating solid will either increase in volume (grow bigger) or melt (become a liquid). A liquid has no fixed shape, but it. High Speed Flows Doyle D. Knight This book presents the basic elements of numerical methods for compressible flows. It is appropriate for advanced undergraduate and graduate students and specialists working in high speed flows. Contents: 1. Governing equations; 2. Mathematical nature of 1-D Euler equations; 3. 1-D Euler equations; 4.
