Wave propagation characteristics of Parareal
The paper derives and analyses the (semi-)discrete dispersion relation of the Parareal parallel-in-time integration method. It investigates Parareal’s wave propagation characteristics with the aim to better understand what causes the well documented stability problems for hyperbolic equations. The analysis shows that the instability is caused by convergence of the amplification factor to the ex...
متن کاملWave Propagation Characteristics on a Covered Conductor
A wave propagation characteristic is very significant to investigate a transient voltage and insulation design of a cable. This paper carries out an experiment and a simulation of wave propagation characteristics on an insulation covered conductor in comparison with a bare conductor. The simulations are carried out using Electro Magnetic Transient Program (EMTP) and Finite Difference Time Domai...
متن کاملComparing Wave Propagation Characteristics of Various Smart Electricity Distribution Networks
In Nordic countries, electricity distribution networks are consisted of underground cables or overhead insulated conductors or mix of both. However, each alternative has its own pros and cons. This chapter concentrates on determining the wave propagation characteristics of single-phase medium voltage (MV) cross-linked polyethylene (XLPE) cable and covered-conductor (CC) overhead electricity dis...
متن کاملWave Propagation and Band-gap Characteristics of Chiral Lattices
Plane wave propagation in a chiral lattice is investigated through the application of Bloch’s theorem. Two-dimensional dispersion relations are estimated and analyzed to illustrate peculiar properties of chiral or non-centrosymmetric configurations and investigate the directional behavior of wave propagation for varying geometric parameters. Special attention is devoted to the determination of ...
متن کاملPlane Wave Propagation Through a Planer Slab
An approximation technique is considered for computing transmission and reflection coefficients for propagation of an elastic pulse through a planar slab of finite width. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is s...
