An estimation method of full scale performance for pulling type podded propellers
International Journal of Naval Architecture and Ocean Engineering, 2014 : This paper presents a new estimation method of full scale propulsive performance for the pulling type podded propeller. In order to estimate the drag of pod housing, a drag velocity ratio, which includes the effects of podded propeller loading and ...

Equilibrium Distribution of Heavy Quarks in Fokker-Planck Dynamics [PDF]
, 1999 We obtain within Fokker-Planck dynamics an explicit generalization of Einstein's relation between drag, diffusion and equilibrium distribution for a spatially homogeneous system, considering both the transverse and longitudinal diffusion for dimension n ...

Theoretical analysis of drag resistance in amorphous thin films exhibiting superconductor-insulator transitions [PDF]
, 2010 The magnetical field tuned superconductor-insulator transition in amorphous thin films, e.g., Ta and InO, exhibits a range of yet unexplained curious phenomena, such as a putative low-resistance metallic phase intervening the superconducting and the ...

Drag Analysis of Three Rudder-Shaped Like Bodies
Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2020 This paper presents an investigation of Rudder Shaped-Like (RSL) hull configurations with low-drag characteristic using the resistance model tests and numerical analysis. The new design of the floating platform using three hulls with a self-manoeuvring system as Unmanned Surface Vehicle (USV) and capable of collecting the same data as a hydrography ...

Aerodynamic Drag Analysis of Superpressure and Zero Pressure Balloons using Large Eddy Simulations (LES) [PDF]
Journal of Applied Fluid MechanicsStratospheric balloons are an essential part of the scientific research community. In previous stratospheric balloon models used for trajectory prediction and station-keeping, the aerodynamic drag has usually been modeled as similar to that of a sphere ...

On-site drag analysis of drafting cyclists
Journal of Wind Engineering and Industrial Aerodynamics, 2021 The aerodynamic drag of a trailing cyclists in a tandem formation is investigated at different lateral and longitudinal separations. A Ring of Fire (RoF) experiment is conducted at the Tom Dumoulin bike park of Sittard-Geleen in the Netherlands. The method is based on stereoscopic Particle Image Velocimetry (Stereo-PIV) measurements followed by ...
