Applications solid-cone spray

Solid-cone spray atomizers usually generate relatively coarse droplets. In addition, the droplets in the center of the spray cone are larger than those in the periphery. In contrast, hollow-cone spray atomizers produce finer droplets, and the radial liquid distribution is also preferred for many industrial applications, particularly for combustion applications. However, in a simplex atomizer, the liquid flow rate varies as the square root of the injection pressure. To double the flow rate, a fourfold increase in the injection pressure is... 

Catalyst(Rocketry). A liq or solid substance which, by its contact with a "monoreactant fluid, increases the breakdown or reaction rate, without itself becoming altered in nature or amount. One of the earliest known rocket applications of a catalyst was in a Ger ATO engine, The "Walter 109-500 . Liquid Ca permanganate was sprayed in the thrust chamber of the motor to make contact with the primary spray of coned H202. The catalyst caused the nearly instantaneous breakdown of this mono -proplnt into hot steam and oxygen. Other catalysts considered or tried include Na...
