Stochastic Drag Analysis via Polynomial Chaos Uncertainty Quantification
51st AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2013 In this paper, uncertainty quantification approaches are applied to aerodynamic data analyzed by a far-field drag breakdown approach. By the use of the drag breakdown approach, total drag of an airfoil configuration can be decomposed into three physical ...

Aerodynamic drag analysis of runners.
Medicine & Science in Sports & Exercise, 1976 A model is presented for the determination of aerodynamic drag forces on runners. The model consists of a series of conjugated circular cylinders, to stimulate the trunk and appendages, and a sphere to stimulate the head. Results are presented for three runners representing respectively, adult American males in the 2.5, 50 and 97.5 percentiles of the ...

Analysis of Drag Reduction Methods and Mechanisms of Turbulent [PDF]
Applied Bionics and Biomechanics, 2017 Turbulent flow is a difficult issue in fluid dynamics, the rules of which have not been totally revealed up to now. Fluid in turbulent state will result in a greater frictional force, which must consume great energy.

Kinematic analysis of the drag flick in field hockey [PDF]
Sports Biomechanics, 2017 Attaining high speed of the stick head and consequently of the ball is essential for successful performance of the drag flick in field hockey, but the coordination pattern used to maximise stick head speed is unknown. The kinematics of the drag flick was

Atmospheric Drag Analysis with the AEROS Satellites
Journal of geomagnetism and geoelectricity, 1979 The approach followed in deriving total gas density at perigee from the orbital decay of the AEROS satellites is described. Numerical integration of the drag force acting on the satellite along the orbit is used in an iterative procedure to compute thermospheric density.

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 ...

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 ...
