HINOJOSA, Alberto; ESPINOSA, Katherine  e  CORREA, Rodrigo. PARTICLE SWARM OPTIMIZATION AND THE MINIMUM ENTROPY CRITERION IN THE OPTIMUM DESIGN OF A HEAT SINK. Rev. ing. univ. Medellín [online]. 2012, vol.11, n.20, pp.203-214. ISSN 1692-3324.

This research paper shows the simulation results of the thermal design of a micro channel heath sink. A minimum entropy generation criterion was used to generate the mathematical model, which was then solved by Lagrange multipliers and by particle swarm optimization (PSO). It was found that due to the extensive number of variables, traditional techniques demand elevated computational resources since it requires solving a system of non-linear equations. This system was solved using the multidimensional Newton-Raphson method, which needs a set of proposed initial solutions, without having technical criteria for choosing it. On the other hand, particle swarm optimization provides a rather simple solution to the problem. Results achieved with both methods are compared.
