Parametric analysis and optimization of entropy generation in unsteady MHD flow over a stretching rotating disk using artificial neural network and particle swarm optimization algorithm

► The first and second law analyzes of an electrically conducting fluid past a rotating disk is studied. ► Homotopy Analysis Method, Particle Swarm Optimization algorithm and ANN are applied for optimization. ► A very good agreement observed between the obtained results and the previously published data. ► For minimizing the entropy generation value a procedure based on ANN and PSO is proposed.
