Electricity generation is a global challenge to be faced by several countries. This has led to the pursuit and development of new clean technologies to sustainable supply of the growing world demand for energy. Currently ...

In this study, three-dimensional transient numerical simulations of the flow around a cross flow water turbine of the type H-Darrieus are performed. The hydrodynamic characteristics and performance of the turbine are ...

In this contribution, unsteady three-dimensional numerical simulations of the water flow through a horizontal axis hydrokinetic turbine (HAHT) of the Garman type are performed. This study was conducted in order to estimate ...

Colombia has a renewable installed capacity of close to 70% in hydroelectric generation. However, especially in dry periods, thermal generation (mostly based on natural gas) has played a dominant role in the country's ...
