In this work, the computational fluid simulation is conducted on the force estimation of the Unmanned Aquatic Vehicle’s Rotor [Hydro-rotor] at the complicated environment. Hydro-Rotodynamic is furthermore complicated field, so the force estimation in and around the rotor is very toughest process. In this regard, an advanced numerical approach is used in this work, which is nothing but the dynamic technique of MRF (Moving Reference Frame) associated in CFD (Computational Fluid Dynamics). The MRF’s implementation and integration is because of representation of the Rotodynamic behavior in the hydrodynamic simulation and thereby the primary outputs are attained with the acceptable category. In numerical simulation phase, CATIA and ANSYS Fluent 16.2 are the tools primarily used for the process of conceptual design and hydrodynamic analysis respectively. Apart from this advanced simulative based results, the standard theoretical approach is also implemented in the Hydro-Rotodynamic domain, in order to estimate power required at critical stage, efficiency, and Hydrodynamic forces. For the validation part, the analytical approach is imposed in this work for the verification of computational outcomes. Additionally grid convergence test are conducted and thereby the verified phases of CFD are picked. Through these validation investigations, the reliability of the CFD’s outcome checked and proved. Finally the comparisons are executed for results of engineering parameters of both numerical simulation and theoretical approaches. Thus the working conditions, propulsive efficiency, power requirement are solidly produced through this advanced simulation, which will be greatly used in the selection of input parameters for Unmanned Aquatic Vehicles’ Rotor.
