“…The left side plane of the stationary zone is specified as a velocity inlet with uniform velocity at all TSR. The right-side plane of the stationary region is designated as an outflow boundary with a pressure set at 1 atmosphere [3,16]. Another four sides of the stationary zone are specified as symmetry.…”

“…The new blade profile was based on the S1048 airfoil section and they observed that the performance of the new blade profile was improved by 14% contrasted to the conventional SHKT. Chaudhari et al [3] have conducted a CFD simulation of a new airfoil-bladed SHKT and contrasted the performance with conventional SHKT. The new airfoil blades of SHKT are NACA6409 airfoil blades with chord length of 158.7 mm, radius of 105 mm and thickness of 100%.…”

Recently, hydrokinetic energy is playing an important role in the production of green energy. It boasts a minimal ecological footprint and holds significant promise for generating energy on a small scale. Savonius Hydrokinetic Turbine (SHKT) acquires the hydrokinetic energy and converts it into useful energy. It has some specific advantages over other hydrokinetic turbines. Two unique thick blade designs have been utilized to replace the traditional semi-circular blades of the Savonius hydrokinetic turbine, resulting in the creation of two novel variants known as SHKT Design-1 and SHKT Design-2. Numerical investigations are carried out to assess and contrast the performance of SHKT Design-1 and SHKT Design-2 with conventional SHKT, with inlet velocity 0.9 m/s at various tip speed ratios between 0.7 to 1.1. The current study demonstrates that, the performance of SHKT is greater compared to SHKT Design-1 and SHKT Design-2. Savonius hydrokinetic turbine has a 10.5% and 7.5% higher maximum coefficient of power compared to SHKT Design-1 and SHKT Design-2 respectively. The flow field generated about the SHKT, SHKT Design-1 and SHKT Design-2 are examined and deliberated upon to evaluate performance across different facets.
