Method for simulating fluid flow and recording medium for performing the method
A method for simulating fluid flow includes: discretizing a space in which a fluid flows into a regular lattice; assuming that fluid particles repetitively move and collide in the lattice; deriving a univariate polynomial equation by comparing the n-th (n is a non-negative integer) order momentum of velocity between the Maxwell-Boltzmann distribution and the discretized Maxwell-Boltzmann distribution; calculating the weight coefficients corresponding to the discrete velocities of the fluid particles based on the univariate polynomial equation; and deriving a lattice Boltzmann model using the weight coefficients. A lattice Boltzmann model with superior stability and accuracy may be derived easily.
