Drop damage ceramic monolith. Pressure drop due to the headers and brick resistance and their relative roles is also identified. Porous ceramic filter indicates the pressure loss is acceptable as it lies between 400 to 500 cpsi which has been widely used in the market. The catalytic converter assembly consists of a monolith with a cell density of 400 cells per square inch cpsi and a wall thickness of 6 5 mil 6 5x10 3 inch. One or two layers of catalyst may be applied and higher no x reduction can be achieved with the use of higher amounts of catalyst two layers european commission and joint research center 2013.
Ceramic wall flow monoliths which are derived from the flow through cellular supports used for catalytic converters became the most common type of diesel filter substrate.

Nevertheless the flow profile of a monolith is different from the accepted lamina r profile which is possibly caused by the high surface roughness of the channel 11. Since the substrate inlet and outlet pressure losses are relatively insignificant in the total catalyst pressure drop there has been little.

An empirical model has also been developed by ekstrom and andersson 14 to predict the pressure drop suitable for one dimensional 1d and 3d simulations. The monolith is insulated using an insulation mat wrapped around the monolith with a thickness of 3 mm. The monolith and insulation are inserted in a stainless steel cylindrical.

Ceramic honeycomb and pleated metal plate monolith designs are general configurations of catalysts u s. Flow distribution within the monolith was found to depend strongly on diffuser performance which is modified strongly by brick resistance. About 1 3 of the way down the main body of the kamado there s an intriguing little knob.
Pulling on the knob reveals a small pullout chute. The above friction factors were compiled from the literature 175 174 laboratory evaluation of ceramic monoliths with square cells and metal monoliths with sinusoidal cells showed very good correlation with the respective coefficients in table 1 173. For simplicity an axisymmetric geometry is chosen. They are distinguished among other diesel filter designs by high surface area per unit volume and by high filtration.
