Abstract
A Boltzmann-based method for simulating a CVI densification process of a composite material is provided. Phase space occupancy is provided in the method, such that a geometrical model can be presented by using the concept of a matrix, and components of a space are distinguished; and a phase space occupancy matrix can directly participate in operation, which is equivalent to a natural division of grids and boundaries, and the boundaries are presented by a phase parameter, which is a natural capturing process. Flow field calculation of the method uses virtual time step calculation, such that a boundary condition can be written in a unified form, thereby improving the programmability.
