Prototype. Testing for Back Pressure

A direct impact catalytic converter that forces all traversing gases to impact on the catalyst covered surface has been developed. Engine exhaust is forced to move through perforated plates. The gas is forced to adopt main flow conditions as it flows via these holes and is then forced to impact on the trailing disc, which has the same hole distribution as the first disc but is offset, so that the moving gas impacts on the solid surface of the following disc. Extreme turbulence is achieved as the gas impacts on the solid surface, coming into direct contact with the catalyst coatings. The gas vortexes down pressure gradients and flows to the nearest hole in the trailing disc. This design is so efficient, that it requires only half a percent of the platinum coatings, needed by conventional catalytic converters, to achieve catalyses.

Direct impaction is achieved via the offset hole arrangement which forces all traversing fluid to impact on the leading face of the trailing odd even disc assembly. The drawings give details of the offset hole arrangement:

To confirm the concept of direct impaction sophisticated computer fluid dynamic analyses was undertaken.

A direct impact smooth flow catalytic converter is also available. This complex geometry device reduces back pressure by minimizing turbulence.

The above technology can be modified to provide extremely efficient homogenizers and no moving part mixers for gaseous mixtures, gas liquid mixtures, liquids and colloidal solutions, paints and many other industrial commercial and laboratory uses.

Particularly useful for spray can mixing of solvent and liquid paint systems. Obviates the need for extended shaking of cans.
