Description:
|
|
The Ideal Flow Machine is designed for students learning elementary ideal flow. The term 'Ideal flow' describes the way in which a fluid (liquid or gas) moves when the effects of compressibility and viscosity are negligible. Ideal flow is often the first type of fluid motion that student engineers and scientists study, because it is the simplest. Large parts of the flows past ships, submarines, cars and light aircraft are closely ideal. |

Beam Deflections
via Computer Algebra Systems |

Vernon S. Hillsman. |
|
Description:
|
|
beam deflections
are considered to be elastic deflections if the
maximum flexural stress in the beam is less than
the elastic limit of the beam material [1]. So,
the design of beams is often based on deflection
characteristics, rather than strength. The
deflection of beams carrying plaster ceilings
must be minimized, or the deflection of the beam
may crack the plaster. Likewise, the deflection
of machine parts must also be kept below certain
tolerances to allow the machine to function properly |

Connection Between the Lattice Boltzmann Equation and the Beam Scheme |
|
|
Author:

Kun Xu,Li-Shi Luo |
|
Description:
|
|
In this paper we analyze and compare the lattice Boltzmann equation with the beam scheme in details. We notice the similarity and differences between the lattice Boltzmann equation and the beam scheme. We show that the accuracy of the lattice Boltzmann equation is indeed second order in space. We discuss the advantages and limitations of lattice Boltzmann equation and the beam scheme. Based on our analysis, we propose an improved multi-dimensional beam scheme. |

On Higher Order Dynamics in Lattice-Based Models Using Chapman-Enskog Method |
|
|
Author:
|
|
Yue-Hong Qian,YE ZHOU |
|
Description:
|
|
In this paper, we investigate the existence of higher order dynamics in lattice-based models. We have identified two conditions that determine whether a model would allow some Burnett-like equations when the Chapman-Enskog expansion is used. These two conditions are the number of the conserved quantities as well as the space and time discretization. We shall demonstrate these conditions by discussing (1) pure diffusion equation, and (2) hydrodynamic equations. While the fact that diffusion equation allows the higher order dynamics can be shown easily, we will illustrate that care must be taken when deriving Burnett-like equations for lattice-based hydrodynamics models using the Chapman-Enskog method. |

A Gas-Kinetic Method for Hyperbolic-Elliptic Equations and its Application in Two-Phase Fluid Flow. |
|
|
Author:

|
Kun Xu |
|
Description:
|
|
A gas-kinetic method for the hyperbolic-elliptic equations is presented in this paper. In the mixed type system, the co-existence and the phase transition between liquid and gas are described by the van der Waals-type equation of state (EOS). Due to the unstable mechanism for a fluid in the elliptic region, interface between the liquid and gas can be kept sharp through the condensation and evaporation process to remove the "averaged" numerical fluid away from the elliptic region, and the interface thickness depends on the numerical diffusion and stiffness of the phase change. A few examples are presented in this paper for both phase transition and multifluid interface problems. |

Gas Evolution Dynamics in Godunov-type Schemes and Analysis of Numerical Shock Instability |
|
|
Author:
|
|
Kun Xu |
|
Description:
|
|
In this paper the authors the gas evolution dynamics of the exact and approximate Riemann solvers, e.g., the Flux Vector Splitting (FVS) and the Flux Difference Splitting (FDS) schemes. Since the FVS scheme and the Kinetic Flux Vector Splitting (KFVS) scheme have the same physical mechanism and similar flux function, based on the analysis of the discretized KFVS scheme the weakness and advantage of the FVS scheme are clearly observed. The subtle dissipative mechanism of the Godunov method in the 2D case is also analyzed, and the physical reason for shock instability, i.e., carbuncle phenomena and odd-even decoupling, is presented. |
