Abstract

The angular light intensity distribution (ALID) at the surface of several elliptical reflector‐photoreactors was determined experimentally using the optically dense potassium ferrioxalate actinometer. The distributions were well correlated by the model
The correlating parameter Ξ² was a function of the ratio of the light source and photoreactor tube diameters.

The theoretical effect of ALID on reactor performance was determined for a reaction which proceeded via direct absorption by the reactant. The ALID effect on performance was most pronounced under conditions of high optical densities and low radial mixing rates of reactant.

The effects of intense sound waves, in a flow duct, on the measurement of static pressure are discussed. It is shown that a conventional arrangement involving a static pressure ''tapping'', consisting of an orifice in the duct wall connected via a tube to a manometer, can lead to the sound field int
