Design of K-Type Propeller Optimized with Lightweight Aluminum Material and Its CFD Analysis for Marine-Based Applications

The aim of this research is to do a CFD investigation on the K-type propeller for enumerating the various performance factors. This paper focuses on the design of rotor blades with the 3D pro-E software and analyzes a K-type rotor in computational fluid dynamics (CFD) analysis to predict the performance parameters such as pressure coefficients, magnitude vector capability, axial velocities, radial velocities, static pressures, and dynamic pressures of the propeller subjected to different loads, and its effect of pitch, rake, and skew formations of the analysis with aluminum material coated with bronze optimized by the K-type inferior design is implemented in this analysis. However, this study proves that aluminum material possesses better exposure to the replacement of conventional rotors to enumerate the dynamic performance. The performance results obtained from the CFD analysis show that the implementation of aluminum bronze with a K-type design gives maximum propulsive efficiency of up to 85% and is nearly 12% better than conventional rotors in terms of noise and cavitation formations. The study also revealed that there is an improvement in thrust coefficient by 5%, torque coefficient by 7%, and improvement in efficiency by 10% as the implementation of K-cap propeller in the field of the marine industry.
