Hydrodynamic characteristics of bodies in channels

Journal of Fluid Mechanics, 1993
The effect of channel walls on the hydrodynamic characteristics of fixed or oscillating bodies is discussed using classical linear water wave theory. Particular attention is paid to the occurrence of trapped modes persisting local to the fixed body and which are manifested in a non-uniqueness of the corresponding forced problem at the trapped mode ...

Hydrodynamic characteristics of cyclone reactors

Powder Technology, 1989
Abstract Recently, cyclones have been used as chemical reactors for example for coal combustion and gasification. In order to provide information needed for cyclone reactor design, the effects of air inlet velocity (6 ∼ 17 m/s), particle (coal-char and glass beads) size (141 ∼ 211 μm), solid loading (0.0 ∼ 0.189 kg/m3) and geometric ratio of cylinder

Hydrodynamic characteristics of a FCC regenerator

Korean Journal of Chemical Engineering, 2003
The hydrodynamic and gas mixing characteristics have been determined in a FCC regenerator (0.48 m I.D.x3.4 m high) with FCC particles. Solids holdup in the dense bed decreases with increasing gas velocity, but it increases in the freeboard region. The bubble/void fraction increases with an increase along the bed height at a given gas velocity and ...

Hydrodynamic Characteristics of Ship Rudders

2020
As discussed in Chap. 2, inland vessels have more complex rudder configurations than seagoing ships. Currently, the rudder profile, the number of rudders, and the spacing between rudders are not considered in the empirical methods for rudder force calculation.

Hydrodynamic Characteristics of Prismatic Barges

Offshore Technology Conference, 1971
ABSTRACT The forces and moments acting on prismatic hulls are presented, for both wave excitation and motions. Using these charts a platform designer can easily calculate the motions of a barge in head seas or beam seas. An example is given to illustrate the procedure for calculating motions.

Characteristics of Water Strider Legs in Hydrodynamic Situations

Langmuir, 2009
This study investigated the forces and the cross-section images of a water strider's leg through experimental observations. In the vertical direction, the spring coefficients were found to be 0.6 N/m for the leg and 0.3 N/m for the water, which provide a water-treading stiffness of 0.2 N/m.

Hydrodynamic Characteristics of a Swimmer’s Hand

Journal of Applied Biomechanics, 1999
The main purpose of this study was to develop a model for calculating forces produced by a swimmer’s hand, with the thumb adducted, accelerating in the direction of flow. The model included coefficients to account for the velocity and acceleration of the hand.

Analytical Study on Hydrodynamic Characteristics

2017
In this chapter, an analytical model is developed for the motion response and wave attenuation of a raft-type wave-powered desalination device. The desalination module of the device is simplified as a Power Take-Off (PTO) system. The analytical solution of diffraction and radiation problem of multiple two-dimensional rectangular bodies floating on a ...

Numerical relativistic hydrodynamics: Local characteristic approach

Physical Review D, 1991
We extend some recent Ishock capturing methodsR designed to solve nonlinear hyperbolic systems of conservation laws and which avoid the use of artifical viscosity for treating strong discontinuities to a relativistic hydrodynamics system of equations.

Chemical composition and hydrodynamic characteristics of turnip peroxidases

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1973
Abstract The chemical composition and hydrodynamic characteristics of four previously purified turnip isoperoxidases, P 1 , P 2 , P 3 and P 7 were determined. The three acid hemoproteins P 1 , P 2 and P 3 are similar in their amino acid and sugar compositions, molecular weight, and relationship between s c 20,w and the protein ...
