Agents in Grid System – Design and Implementation

system of numerical particles that move according to the laws of mechanics and collide according to stochastic rules based on the intermolecular potential. This method has been successfully applied in aerospace engineering. A challenge is to extend the method to applications, e.g., low Mach number flows, where the signal-to-noise ratio is small. Some recent results related to weighted particles will be presented. A second application area of stochastic particle methods is chemical engineering, e.g., soot modelling, production of nanoparticles, granulate processing. The governing equations are various generalizations of Smoluchowski’s coagulation equation, including fragmentation, growth, inception, and other processes. An application related to a five-dimensional granulation model will be considered. A particular challenge is the strongly fluctuating number of numerical particles in the direct simulation method. Alternatives are provided by methods using weighted particles.
