Claim One:
1. A method for simulating fluid flow comprising: discretizing a 1-dimensional space in which fluid flows into a regular lattice; assuming that fluid particles of the fluid repetitively move and collide in the regular lattice; deriving a univariate polynomial equation using a Gaussian Gamma function by comparing an n-th order momentum of velocity between a Maxwell-Boltzmann distribution and a discretized Maxwell-Boltzmann distribution including unknown weight coefficients w i corresponding to given discrete velocities v i , wherein n is a non-negative integer and wherein the discrete velocities v i and the unknown weight coefficients w i are defined as follows: 
 v 1 =0 ,v 2i >0, 
 v 2 <v 4 <. .. <v q−1 , 
 v 2i =−v 2i+1 , 
 and 
 w 2i =w 2i+1 for i=1, 2,. .. , [q/2], wherein [q/2] is the largest integer that is smaller than or equal to q/2, and q is an odd number; calculating the unknown weight coefficients w i corresponding to the given discrete velocities v i of the fluid particles based on the comparison; and deriving a lattice Boltzmann model using the calculated weight coefficients w i the given discrete velocities v i and the discretized Maxwell-Boltzmann distribution, the lattice Boltzmann model for simulating the flow of the fluid into the regular lattice.
