Modeling on Directional solidification of Silicon for Solar Cell Applications
The Directional Solidification is a very important technique for growing high quality multi-crystalline silicon at large scale for PV solar cells. The physics governing the growth of multi-crystalline silicon in the Directional Solidification System involves complex non-linear transport phenomena including but not limited to heat transfer, solidification, thermal stress development, and the for...
متن کاملCellular instabilities in directional solidification
2014 We have studied the morphology of the solid-liquid interface during the directional solidification of thin (5-150 03BCm) samples of a dilute binary mixture (CBr4/~ 0.1 % Br2) . Above a critical pulling speed, for a given temperature gradient and solute concentration, the interface, initially planar, breaks down into a periodic cellular pattern. The bifurcation from a planar to a cellular s...
متن کاملCellular automaton modeling of pattern formation in interacting cell systems
Cellular automata can be viewed as simple models of spatially extended decentralized systems made up of a number of individual components (e.g. biological cells). The communication between constituent cells is limited to local interaction. Each individual cell is in a specific state which changes over time depending on the states of its local neighbors. In particular, cellular automat on models...
متن کاملModeling of Macrostructure Formation during the Solidification by using Frontal Cellular Automata
Prediction of the microstructure and properties is one of the most important problems in materials science. There are different methods that are used for modeling of the microstructure evolution, among them are the front tracking method (Thompson et al., 1987; Frost et al., 1988), the phase-field models (Fan & Chen, 1997), the cellular automata (CA) models (Davies, 1997), vertex models (Weygand...
متن کاملCellular Automaton Modeling of Passenger Transport Systems
Jamming phenomena are observed everywhere in our daily live. These stagnations in flow occur not only on highways, but also in stadiums, in public transportation like buses and trains, in the world of the Internet, and even in our bodies. Almost everyone will have a negative image of a “jam”, which means the clogging of the flow of traffic, however we do have positive reactions to some kinds of...
