Resumen

This article presents a brief review of the historical evolution of the numerical flow simulations for hydraulic machinery in the last decades. From the early beginning in the use of numerical techniques to analyze the behavior of the flow in these kind of machines, back to the early 70s, until nowadays, a lot of improvements and modifications in the strategies have allowed to reach important progress towards the better knowledge and design of these turbomachines. The most relevant methodological changes experienced along the years, including the approximation degree (turbulent models and solved scales), main goals of the different approaches, calculation capabilities and model computational loads, are all explained. Special focus is made on the state-of-the art in all these features. The final part of the article shows future challenges and depicts a possible understanding on the different options that may occur in the use of numerical techniques to study the flow in hydraulic turbomachines.
