Effect of β-PVDF Piezoelectric Transducers’ Positioning on the Acoustic Streaming Flows
Micromachines, 2014 This paper reports the numerical and experimental analysis of the acoustic streaming effect in a fluidic domain. The actuation of a piezoelectric transducer generates acoustic waves that propagate to the fluids, generating pressure gradients that induce ...

Spectrum synthesis for magnetic, chemically stratified stellar atmospheres [PDF]
arXiv, 2007 Modern investigations of magnetic chemically peculiar stars reveal a variety of complex processes in their atmospheres. Realistic spectrum synthesis modelling of these objects has to take into account anomalous chemical composition, strong magnetic field and chemical stratification.

Relaxation Phenomena in a Bistable Chemical System
, 1984 A theoretical investigation is presented of the relaxation dynamics of a simple model which gives a near-quantitative description of the iodate-excess arsenous acid systems (1). Near the hysteresis limits (K≳ K1, K≲ K2, K= input flow rate) and near the critical point K an exact expression is obtained for the nonlinear response to a sudden change of the

Pulsations, chemical composition and multiplicity in main-sequence A- and F-type stars [PDF]
arXiv, 2009 The region in the HR-diagram where the main sequence intersects the classical instability strip hosts A- and F-type stars exhibiting a rich variety of physical phenomena, such as pulsations on various time scales and chemical peculiarities. We aim to investigate the occurrence of these phenomena among suspected binary systems in this region of the HR ...

Numerical Evaluation of Cuspoid and Bessoid Oscillating Integrals for Applications in Chemical Physics [PDF]
Khimicheskaya Fizika, 2004, Volume 23, Number 2, pages 13-19, 2004 Oscillating integrals often arise in the theoretical description of phenomena in chemical physics, in particular in atomic and molecular collisions, and in spectroscopy. A computer code for the numerical evaluation of the oscillatory cuspoid canonical integrals and their first-order partial derivatives is described.

Phase separation of chemokinetic active particles [PDF]
arXivMotility-induced phase separation (MIPS) is a well-studied nonequilibrium collective phenomenon observed in active particles. Recently, there has been growing interest in how coupling the self-propulsion of active particles to chemical degrees of freedom affects MIPS.
