Experimental investigation of vortex ring evolution in polymer solution [PDF]
arXiv, 2019 We have conducted experiments on the effect of polymer solutions on the formation and propagation of vortex rings. We study this effect in aqueous solution of hydrolyzed polyacrylamide (PAMH) at different concentrations. Addition of PAMH imparts shear-rate dependent viscosity and elasticity to the solvent. With increasing concentration of PAMH both the

Hot piston ring/cylinder liner materials: Selection and evaluation [PDF]
In current designs of the automotive (kinematic) Stirling engine, the piston rings are made of a reinforced polymer and are located below the pistons because they cannot withstand the high temperatures in the upper cylinder area.

Vortex ring pinchoff in the presence of simultaneously initiated uniform background co-flow [PDF]
, 2003 Vortex rings were formed with a piston-cylinder mechanism in the presence of uniform background co-flow supplied through a shroud surrounding the cylinder. The jet and co-flow were started simultaneously. Ratios of the co-flow to jet velocity (Rv) in the

Modal operators and toric ideals [PDF]
arXiv, 2017 In the present paper we consider modal propositional logic and look for the constraints that are imposed to the propositions of the special type $\Box a$ by the structure of the relevant finite Kripke frame. We translate the usual language of modal propositional logic in terms of notions of commutative algebra, namely polynomial rings, ideals, and ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study addresses significant process challenges associated with the reactive nature of hemicellulose‐derived furan intermediates in aqueous mediums. A continuous agitated cell reactor was used to intensify the extractive reaction using methyl isobutyl ketone as an extractive phase to isolate in situ the furan products obtained by ...
