%X this work intends to analyze the application and execution time of a numerical algorithm that simulates incompressible and isothermal flows. it was used the explicit scheme of the "characteristic based split" (cbs) algorithm and the "artificial compressibility" (ac) scheme for coupling pressure-velocity equations. the discretization was done with the finite element method using a bilinear elements grid. the free software gnu-octave was used for implementation and execution of routines. the results were analyzed using the classic lid-driven cavity problem. this work shows results for tests with several reynolds' number. the results for these tests show a good agreement when compared with previous ones obtained from bibliography. the code runtime's analysis shows yet that the matrix's assembly is the part of greater consumption time in the implementation.
