International Journal for Numerical Methods in Fluids() A linear system solver based on a modified Krylov subspace method for breakdown by: The nonsymmetric Lanczos method can be used to compute eigenvalues of large sparse non-Hermitian matrices or to solve large sparse non-Hermitian linear systems.

However, the original Lanczos algorithm is susceptible to possible breakdowns and potential instabilities. An implementation of a look-ahead version of the Lanczos algorithm is presented that, except for Cited by: The paper discusses possible ways of developing accurate and efficient finite volume methods for complex, incompressible flows.

The issues of boundary-fitted grid generation, choice of coupled or uncoupled procedures, Cartesian or grid-aligned velocity components, staggered or non-staggered variable arrangement, discretization methods, solution algorithms and Cited by: Christopher B.

Umminger, in Analog Circuit Design, Volume Three, Generating an output DC voltage from an input voltage that can vary both above and below the regulation point is a challenging power supply problem with a variety of solutions. Flyback or forward converters work well, but are difficult to use if a small and efficient solution is desired at high output currents.

Brief description of flow solution algorithms Several distinct types of flow solution algorithms are potentially applicable to the prediction of the nominal wake. These algorithms use different methods for discretising the RANS equations which fall into three broad categories: finite difference, finite volume and finite element.

This book consists of 37 articles dealing with simulation of incompressible flows and applications in many areas. It covers numerical methods and algorithm developments as well as applications in aeronautics and other areas. It represents the state of the art in the field.

Contents: Navier–Stokes Solvers; Projection Methods; Finite Element. Equation () states that for incompressible flows the net flow across any control volume is zero, i.e., “flow out” = “flow in”.

Note also that Dq=Dt ¼ 0 does not imply that q is the same everywhere (although this happens to be the case in many hydraulic applications), but that q does not change along a streamline. The motility mechanism of prokaryotic organisms has inspired many untethered microswimmers that could potentially perform minimally invasive medical procedures in stagnant fluid regions inside the human body.

Some of these microswimmers are inspired by bacteria with single or multiple helical flagella to propel efficiently and fast. For multiple flagella configurations, the Cited by: 1.

The goal of this paper is to contribute to the design of high-performance mesocombustors, a field currently under rapid development, in particular for propulsion, e.g., for UAVs, and micro/meso-electrical power generators.

This study is focused on a cylindrical combustor of 29 cm3, fuelled by methane and air, which provides 2 kW of thermal power. The device was entirely designed Cited by: Approximate solutions have recently been proposed in the book and papers of Podlubny in which the solution obtained with approximate methods is compared to the exact solution.

In this paper we consider the reformulation of the Bagley-Torvik equation as a system of fractional differential equations of order $1/2$. This just means that these boundaries do not affect the flow in any possible way. Grid Independence Study An initial grid independence study was performed in order to be sure that the flow solutions obtained in the later sensitivity analysis were consistent and independent of the grid used for discretizing the flow domain.

It is ideally suited for incompressible to mildly compressible flows. The conservation of mass, momentum and energy in fluid flows are expressed in terms of non-linear partial.Issuu is a digital publishing platform that makes it simple to publish magazines, catalogs, newspapers, books, and more online.
