Influence of drag and turbulence modelling on CFD predictions of solid liquid suspensions in stirred vessels
2014
Abstract Suspensions of solid particles into liquids within industrial stirred tanks are frequently carried out at an impeller speed lower than the minimum required for complete suspension conditions. This choice allows power savings which usually overcome the drawback of a smaller particle-liquid interfacial area. Despite this attractive economical perspective, only limited attention has been paid so far to the modelling of the partial suspension regime. In the present work two different baffled tanks stirred by Rushton turbines were simulated by employing the Eulerian-Eulerian Multi Fluid Model (MFM) along with either the Sliding Grid algorithm (transient simulations) or the Multiple Refe…
Shooting methods for 1D steady-state free boundary problems
1993
AbstractIn this note, we present two numerical methods based on shooting methods to solve steady-state diffusion-absorption models.
An omics perspective to the molecular mechanisms of anticancer metallo-drugs in the computational microscope era
2017
Introduction: Metallo-drugs have attracted enormous interest for cancer treatment. The achievements of this drug-type are summarized by the success story of cisplatin. That being said, there have been many drawbacks with its clinical use, which prompted decades worth of research efforts to move towards safer and more effective agents, either containing platinum or different metals. Areas covered: In this review, the authors provide an atomistic picture of the molecular mechanisms involving selected metallo-drugs from structural and molecular simulation studies. They also provide an omics perspective, pointing out many unsettled aspects of the most relevant families of metallo-drugs at an ep…
Pattern Formation During Dry Corrosion of Metals and Alloys
1987
About corrosion of metals and alloys, many exciting problems are not entirely solved. One of them concerns some morphological features such as, for example, stratified periodic structures that may appear, for example during the oxidation or sulfidation of metals and alloys. In this context, a high temperature corrosion kinetics is interpreted in terms of a bistable chemical system which can oscillate spontaneously if a feedback effect could exist. Some models analyse these patterning from a theoretical point of view. Stability analyses of the uniform standard steady state point out that it can be unstable by bifurcation and give rise to multilayered scales. Some non linearities, peculiar to…
Joseph Conrad-Korzeniowski, czyli polska dusza w literaturze angielskiej
2016
Joseph Conrad wniósł do literatury angielskiej prawdziwie polską duszę i fantazję. Ostatni z polskich romantyków, jak sam siebie nazwał, wprowadził do światowej literatury polskie dylematy, rozterki i wątpliwości, a także tęsknoty i pragnienia. Conrad przeniósł polskie doświadczenie na poziom uniwersalny i takim owo doświadczenie również uczynił. Rozmaite relacje współczesnych ukazują, jak niejednokrotnie trudno było odnaleźć się Polakowi w anglosaskiej rzeczywistości, i z jakimi przeciwnościami musiał się zmierzyć.
W sprawie zgodności z Konstytucją RP powoływania sędziów – członków Krajowej Rady Sądownictwa przez Sejm
2022
Przedmiotem niniejszego tekstu jest ustalenie, czy art. 9a ustawy o Krajowej Radzie Sądownictwa jest zgodny z Konstytucją RP. W celu udzielenia odpowiedzi na to pytanie przeanalizowano relacje, jakie powinny panować pomiędzy poszczególnymi władzami w systemie opartym o zasadę podziału władz. Następnie rozwiano wątpliwości co do tego, czy KRS jest organem występującym w pionie władzy sądowniczej. Ostatecznie stwierdzono, że w RP Sejm nie powinien mieć innych kompetencji kreacyjnych wobec organów władzy sądowniczej, niż tylko te, które wyraźnie przewiduje Konstytucja RP. W przeciwnym razie izba postawiona jest w pozycji nieuzasadnionej supremacji względem judykatywy, a władza sądownicza nie d…
Determinants of Ready-to-eat Products Purchase Intentions: An Empirical Study among the Italian Consumers
2018
The considerable diffusion of ready-to-eat products has focused attention on the reasons for their increasingly prominent success in the market. Although their prices are much higher than the prices of simple raw materials, their consumption has increased rapidly and with no end in sight, a situation that has challenged the conclusions of the classical literature on the importance of price and/or income in consumer decisions. In fact, more recent literature has broadened the classical vision by introducing potential additional variables that could influence consumer choice of certain foods. These variables, however, are not always easy and clear to identify because they reflect the cultural…

Automatic Secondary Cooling Control for the Continuous Casting Process of Steel
1991
Two simulation models for finding the optimal secondary cooling strategy in continuous casting process are presented. The first one is a two-dimensional off-line model for optimizing steady state casting operation. The second one is a one-dimensional model which can be used for simulating casting operation in real-time during varying casting conditions.
On Fixed Point (Trial) Methods for Free Boundary Problems
1992
In this note we consider the trial methods for solving steady state free boundary problems. For two test examples (electrochemical machining and continuous casting) we discuss the convergence of a fixed point method. Moreover, using the techniques of shape optimization we introduce a modification of the method, which gives us superlinear convergence rate. This is also confirmed numerically.
