OBJECTIVE: to address the importance of computational simulation in the design and operation of mechanical cooling towers, highlighting the influence of climatological variables and cooling efficiency. METHOD: the Tchebychev, Ordinate, and Mickley calculation procedures were applied, with particular emphasis on the accuracy of the mass transfer coefficient, which was validated using experimental data. RESULTS: the calculations revealed significant differences in the mass and energy transfer coefficients, allowing for the development of a specific formula to optimize the calculation systems based on operational conditions. These results were validated through experimental correlation, showing that the mass transfer rate is directly influenced by the mass flow rate of water and air per unit area. CONCLUSION: computational simulation and the evaluation of mechanical draft cooling towers are key tools for improving the efficiency and performance of these systems. Correct consideration of climatological variables, validation with experimental data, and precise determination of the mass transfer coefficient are essential elements. Comparison with other calculation methods showed that the Ordinate method is the most efficient, highlighting the importance of selecting the appropriate calculation system based on the specific conditions of each application.
