Analysis for an N-stepped Rayleigh bar with sections of complex geometry
TL;DR: In this article, the vibrations of an N-stepped Rayleigh bar with sections of complex geometry, supported by end lumped masses and springs, were analyzed and two types of orthogonality for the eigenfunctions were obtained.
Journal ArticleDOI
Parametrically defined nonlinear differential equations, differential–algebraic equations, and implicit ODEs: Transformations, general solutions, and integration methods
TL;DR: The study deals with nonlinear ordinary differential equations defined parametrically by two relations, which arise in fluid dynamics and are a special class of coupled differential–algebraic equations.
Journal ArticleDOI
New methods of the mass and heat transfer theory—I. The method of asymptotic correction and the method of model equations and analogies
Andrei D. Polyanin,V.V. Dtl'man +1 more
TL;DR: In this paper, two new approximate analytical methods are suggested to investigate the heat and mass transfer problems: asymptotic correction and model equations and analogies, which can also be successfully used to construct approximate (engineering) formulae in the problems of chemical engineering.

Diffusion to a chain of drops (bubbles) at large péclet numbers
TL;DR: In this article, the problem of diffusion of a substance, dissolved in a flow, to absorbing drops (bubbles) moving one after another in a viscous incompressible fluid is investigated.
