The current work presents the numerical prediction method to determine small-scale
propeller performance. The study is implemented using the commercially available …

Gene tree discordance is now recognized as a major source of biological heterogeneity.
How to deal with this heterogeneity is an unsolved problem, as the accurate inference of …

When a pump-jet propeller rotates at high speeds, a tip vortex is usually generated in the tip
clearance region. This vortex interacts with the main channel fluid flow leading to the main …

This paper describes progress made on the new design and analysis of a twin-propeller
(front and rear) with duct. Major advantage of this design is that the Unmanned Aerial …

In this study an attempt has been made to study the hydrodynamic performance of pumpjet
propulsor. Numerical investigation based on the Reynolds Averaged Navier–Stokes (RANS) …

In the maritime industry, propellers are the most commonly used form of propulsion and are
core to the optimum performance of a ship. Generally, the performance characteristics of a …

In this study, the SST k− ω turbulence model and the sliding mesh technology based on
RANS method have been adopted to simulate the exciting force and hydrodynamic of a …
