| Abstract;A complex boundary model is proposed. This model is implementation method of boundary detection in continuous-velocity lattice-gas model. A continuous-velocity lattice-gas model is flow analysis by using particle motion, resembles primitive lattice-gas model and lattice-Boltzmann model. These models were applied to boundaries and interfaces with complex geometry, frequently. In this study, to treat boundaries with complex geometry in a continuous-velocity lattice-gas model, the authors introduce cells to divide a system into sub space. In two-dimensional system, boundaries are consist of edges of cells, therefore small grained cells can approximate boundaries with complex geometry. Moreover by using recursive function can keep implementation simply, and to ensure extension of this solver. The proposed model was developed and was applied optimizing automatic design to estimate benchmark test. This system in benchmark test has 8 channels which are honeycomb structure. This system was optimized by GA algorithm. As a result, in the difference of flow rate between channels, optimal channels are smaller than before optimal channels. (author abst.) |
