The aim of this study is to develop a genetic algorithm for parameter estimation of a jet flow mathematical model, considering its axial velocity. A jet flow consists of the injection of air through a pipe or nozzle of small section. The study of these flows is useful for the design of dust separators in which this type of flows are common. Genetic algorithms are used to estimate the parameters of the velocity model, proposing different alternatives for the genetic operators. The parameters are also estimated by solving a maximum likelihood optimization problem using a successive quadratic programming strategy. The optimal representation achieved is compared against experimental data from literature and previous estimations. The proposed genetic algorithm proves to be an efficient technique for solving the parameter estimation problem.
