Abstract Cross-flow hydro turbines (CFHTs) are generally used in micro hydraulic power plants due to their simplicity in design and fabrication, moderate efficiency, ease of maintenance. The CFHT can be used in low flow and low head conditions with an efficiency of around 90% at rated conditions. However, the efficiency of the CFHT can further be improved by changing its geometric parameters Hence, in the present investigation, 3D unsteady simulations are performed in order to locate the exit blade angle (β2) with the intention is to improve the efficiency of the turbine. In the proposed investigation, the multi-physics FVM solver ANSYS Fluent has been used with the help of the SST k-ω turbulence model to carry out the unsteady simulations. The 3D unsteady simulations are performed by varying the exit blade angle (β2) from 60° to 90° to improve its efficiency when the rotational speed is fixed with the number of blades being 20. From the unsteady simulations, the maximum efficiency of the CFHT is at the exit blade angle (β2) = 80°.

Bulb Turbine

Tubular hydropower station is a better way in the development of low-head hydraulic power resources. More and more people begin to study the tubular turbine in depth with the development of hydraulic power recourses in the direction of low head and large capacity. With the unique structural features and adaptive head range of tubular turbine, its development is very fast in recent years. The strength analysis of a tubular turbine is an important research aspect with the increasing of its capacity. Bulb turbine is one of the main types of tubular turbines. This paper uses CATIA software and finite element analysis to analyze and calculate the strength and deformation of key components of a bulb turbine, so as to ensure the bulb turbine's safe and reliable operation.
