Abstract	Two-phase gas-liquid slug flow is present in several industrial enterprises, especially in the oil industry where the flow of oil, gas and solid particles are frequent. Slug flow is characterized by the intermittent succession of a liquid slug followed by an elongated gas bubble. Some numerical models for the simulation of this flow pattern can be found in the literature. In this work, a slug tracking model is utilized. Simulations for horizontal flows of air and water in pipes with an internal diameter of 26 mm and lengths of up to 1500 m were performed, varying the inflow frequency of the bubbles in the pipe in all simulations so as to verify the influence of the frequency variation on the flow development,. The role of each correlation for the wake effect on the simulator was evaluated along the tube, and three comparisons between the obtained results were made, disregarding the wake effect and using the correlations proposed by Grenier (1997) and Rodrigues (2008). It was shown that the wake effect influences the time required for the flow to develop. In the analyses performed without the application of the wake effect, the flow developed and stabilized faster than when those correlations were applied.
