The behavior of rope-guided conveyances is so complicated that the rope-guided hoisting system hasn't been understood thoroughly so far. In this paper, with user-defined functions loaded, ANSYS FLUENT 14.5 was employed to simulate lateral motion of rope-guided conveyances in two typical kinds of shaft layouts. With rope-guided mine elevator and mine cages taken into account, results show that t...

In numerical computations of astrophysical flows one frequently has to deal with situations which require the use of a corotating coordinate system. Then, in addition to the centrifugal force, the Coriolis terms have to be included in the Navier-Stokes equations. In usual numerical treatments of solving the equations of motion these non-inertial forces are included explicitly as source terms. I...

An adaptive neural network controller for autonomous underwater vehicles (AUVs) is presented in this paper. The AUV model is highly nonlinear because of many factors, such as hydrodynamic drag, damping, and lift forces, Coriolis and centripetal forces, gravity and buoyancy forces, as well as forces from thruster. In this regards, a nonlinear neural network is used to approximate the nonlinear u...

Higdon-type non-reflecting boundary conditions (NRBCs) are developed for the 2-D linearized Euler equations with Coriolis forces. This implementation is applied to a simplified form of the equations, with the NRBCs applied to all four sides of the domain. We demonstrate the validity of the NRBCs to high order. We close with a list of areas for further research. Published by Elsevier B.V.

Using a simple model we investigate how the flow field in a contact binary can alter its topology under the influence of Coriolis forces. In the case studied, closed streamlines form over a relatively large area. This result causes us to review critically the argument that all surface streamlines can meet in a stagnation point, leading to a constant Jacobi energy over the whole surface. A gener...

A set of Neural Networks learns matrix components representing mass coupling coriolis and friction forces in an inverse robot model While obtaining training data from speci c random trajectories the inverse model becomes highly precise over the entire robot working range Global model precision and subsequently L stability for a controller using the networks in the feedback loop following the le...

A comprehensive hydrodynamic model, COMCOT-S, has been aimed at transport reversal in the Taiwan Strait during the period of Typhoon KROSA in 2007. The numerical model is originally based on COMCOT, and a parametric wind model with atmospheric sub-model is imbedded in COMCOT-S for simulating the typhoon-induced currents. The transport characteristics through the Taiwan Strait under the influenc...
