Characterization of the Mean First-Passage Time Function Subject to Advection in Annular-like Domains

open access: yesMathematics, 2023
Cell migration in a biological medium towards a blood vessel is modeled, as a random process, sucessively inside an annulus (two-dimensional domain) and an annular cylinder (three-dimensional domain).

Heat Transfer by Mixed Convection in the Opposing Thermally Developing Flow in a Vertical and Inclined Annulus

open access: yesTikrit Journal of Engineering Sciences, 2011
Combined convection heat transfer in an inclined (ψ=60o) and vertical (ψ=90o) annulus has been experimentally studied for opposing thermally developing and thermally fully developed laminar air flows with adiabatic inner tube and uniformly heated outer ...

HEAT TRANSFER ENHANCEMENT AND PRESSURE DROP OF GROOVED ANNULUS OF DOUBLE PIPE HEAT EXCHANGER

open access: yesActa Polytechnica, 2017
This investigation was performed to experimentally investigate the enhancement of heat transfer and the friction of an annulus in a double pipe heat exchanger system with rectangular grooves in the turbulent flow regime.

On the degree of holomorphic mappings from an annulus into an annulus [PDF]

open access: yesUkrainian Mathematical Journal, 2004
Summary: We establish an estimate for the degree of a holomorphic mapping \(f: K_1\to K_2\) (here, \(K_1\) and \(K_2\) are doubly-connected domains) in terms of the modulus of a family of curves in \(K_2\). This estimate generalizes a result obtained by \textit{S. Kobayashi} [Hyperbolic manifolds and holomorphic mappings.

On the Szegő kernel of an annulus [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
In this paper we introduce a class of reproducing kernels of an annulus. Using the properties of the theta functions, we obtain a set of functional equations involving these kernels. We discuss some extremal problems associated with the functional equations.

Steady streaming effect on the flow of a couple stress fluid through a constricted annulus

open access: yesArchives of Mechanics, 2012
The oscillatory flow of an incompressible couple stress fluid through an annulus with mild constriction at the outer wall is considered. The mean pressure drops and the mean wall shear stress are calculated across the constricted region.

The Carathéodory metric of the annulus [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
An explicit formula is given for the Caratheodory metric of the annulus in the complex plane. The infinitesimal Caratheodory metric, which is just the norm of the differentiation at a point regarded as a functional on the algebra of holomorphic functions, is also determined.
