Mechanism on Ware Soiling with Silica Scale

Faecal soiling and anal achalasia.

Automotive Soiling Simulation Based On Massive Particle Tracing

In the automotive industry Lattice-Boltzmann type flow solvers like PowerFlow from Exa Corporation are becoming increasingly important. In contrast to the traditional finite volume approach PowerFlow utilizes a hierachical cartesian grid for flow simulation. In this case study we show how to take advantage of these hierarchical grids in order to extend an existing Lattice-Boltzmann CFD environm...

Investigation on Mechanism of Cordierite Formation from Nano Silica-Magnesium chloride-Reactive Alumina

Cordierite ceramics are used as refractory materials and kiln furnaces tools due to their very low coefficient of thermal expansion, high corrosion resistance and excellent thermal shock resistance. The aim of the present work was to synthesis of cordierite with raw materials including nano silica, magnesium chloride and reactive alumina. The synthesis procedure is done at solid state. Mechanis...

Mechanism and Prevention of Scale Formation in Boilers

Nucleate boiling heat transfer coefficients may be strongly reduced by scale formation, even for conditions where the bulk foulant concentration is well below the saturation concentration. Due to the mechanism of micro-layer evaporation, the local concentration at the heat transfer surface can be considerably increased, causing the formation of scale and changes in bubble frequency and bubble d...
