Abstract: Methods and apparatus for high shear reacting and/or mixing of moving fluid streams of materials employ an interdiffusing and reacting zone formed in th e space between two stationary surfaces (30, 32), the surfaces being spaced (2 2, 22B) apart a maximum distance of the sum of the thicknesses of the back-to- back boundary layers of the materials and/or resulting materials on the surfaces, to a value such that any third layer between the two boundary laye rs is too thin to support agitation characterized by turbulent convection and/or to cause channeling. The materials are interdiffused by high speed laminar shear produced by the flow of the materials rather than mixed by macroscopic convection, the materials being driven by high velocity inlet feeds (24, 26) , auxiliary high pressure gas flow pumped into the reaction/mixing zone, or auxiliary high-pressure gas flow created as an evolving gaseous by product o f any chemical reaction that may occur.

Abstract: Methods and apparatus for processing materials employ two cylindrical members, one mounted within the other, defining an annular processing chamber. Preferably, the outer member is stationery (stator), while the inner rotates (rotor). The radial spacing between the stator inner surface and the rotor outer surface is equal to or less than the back-to-back radial thicknesses of the two laminar boundary layers formed on the two surfaces by the material being processed. The surfaces are made smooth, as by buffing to a finish of not more than 10 microinches. This structure inhibits formation of Taylor vortices in the processing passage, which cause unstable flow and consequent incomplete mixing. Preferably, the relative velocity between rotor and stator surfaces is at least 1.2 meters per second. The surfaces may be coated with catalysts. Transducers may be provided to apply processing energy, such as microwave, light or ultrasonic waves, through the stator wall.

Abstract: Procedimiento para el procesado de materiales en una trayectoria de flujo, el procedimiento comprendiendo: - proporcionar un aparato para el procesado de dichos materiales comprendiendo por lo menos una admisión (14) para el material que se va a procesar y por lo menos una salida (52) para el material procesado, dichas admisión (14) y salida (16) estando respectivamente colocadas en correspondencia con los extremos opuestos de dos elementos cilíndricos del aparato (30, 42) montados para el giro relativo de uno con respecto al otro, dichos elementos (30, 42) definiendo dos superficies suaves próximamente separadas (46, 48) que proporcionan un paso de procesado anular (44) que constituye la trayectoria del flujo para el material desde dicha admisión (14) hasta dicha salida (52); - el paso de los materiales que se van a procesar a través de dicho paso de procesado anular (44), por lo que el material que está siendo procesado fluye en dicho paso de procesado (44) formando la respectiva capa límite laminar en cada una de dichas superficies suaves próximamente separadas (46, 48), el grosor () de dicha capa límite estando determinado mediante la ecuación: en donde NRx es el producto de la longitud x de la trayectoria y la velocidad del flujo dividida por la viscosidad cinemática del material que se va a procesar, en el que la separación radial entre las dos superficies (46, 48) es igual o menor que el grosor radial adosado de las dos capas límite, y en el que la suavidad de dichas superficies (46, 48) es inferior a 0, 254 micras, de modo que se inhibe la formación de vórtices de Taylor en el paso de procesado (44).
