Numerical Investigation of Liquid Jet Breakup in Rotary Atomizer

open access: yesChemical Engineering &Technology, EarlyView.
This study presents a numerical analysis of liquid jet breakup in rotary atomization. By comparing different boundary conditions and focusing on gas–liquid interactions, the simulation reveals nonlinear instabilities that govern droplet formation.

Linear Independence of 𝑞-Logarithms over the Eisenstein Integers

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2010
For fixed complex 𝑞 with |𝑞|>1, the 𝑞-logarithm 𝐿𝑞 is the meromorphic continuation of the series ∑𝑛>0𝑧𝑛/(𝑞𝑛−1),|𝑧|1,𝑐≠𝑞,𝑞2,𝑞3,…. In 2004, Tachiya showed that this is true in the Subcase 𝐾=ℚ, 𝑞∈ℤ, 𝑐=−1, and the present authors extended this result to ...

Experimental studies on multi‐scale data‐driven methods within the framework of structural health monitoring

open access: yesCivil Engineering Design, EarlyView.
Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

Let's forget about the pairing

open access: yesMoldavian Journal of the Physical Sciences, 2014
The algebraic formulation of a Wick's theorem that allows one to present the vacuum or thermal averages of the chronological product of an arbitrary number of field operators as a determinant (permanent) of the matrix is proposed.

On the divisibility of the class number in an algebraic number field

open access: yes, 1968
$c$ in the absolute ideal class group $C_{K}$ of $K$, and also means that there exists an unramified abelian extension field of degree $c$ over $K$. Therefore, the problem to investigate which number may be a factor of the ideal class number of $K$ is ...

Stereodynamism in Chiral Polyaromatic Phosphepines

open access: yesChemistry – A European Journal, EarlyView.
Stereodynamism of phosphahelicenoid scaffolds can be used to afford diastereoisomers of polyaromatics fused with a chiral seven‐membered P‐ring. In particular, a complex interplay between the inversion at the P centre and helicenoid epimerization, as well as a competition with a rearomatization reaction, takes place.

Optimal control of axial dispersion tubular reactors with recycle: Addressing state‐delay through transport PDEs

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
The boundary‐regulated distributed parameter system of an axial dispersion tubular reactor with delayed recycle is showcased, along with the optimal observer‐based control strategy developed using a late‐lumping method for its stabilization. Abstract The optimal control of an axial tubular reactor with a recycle stream is addressed as a key type of ...
