The aim of the study was to evaluate corrosion properties three different grades high-speed steel following a heat treatment procedure involving deep cryogenic after quenching and investigate how these are connected microstructure hardness material. steels measured, microstructural were determined through observation metallographically prepared using scanning electron microscopy. These studies complemented evaluation by use potential measurement linear polarization in sodium tetraborate...
This article provides a comprehensive review and evaluation of the selective catalytic reduction (SCR) nitrogen oxides (NOX) using ammonia as reducing agent in flue gases produced by combustion hydrogen or with air. Over years, density functional theory calculations (DFT) have been used extensively to complement experimental results, emphasis on understanding adsorption modes reaction mechanisms. Recent advances this field led shift from non-periodic more accurate periodic models. It has...
The lyophilization of lactose and mannitol aqueous solutions was investigated with an emphasis on analyzing the effects controlled nucleation, temperature pore size distribution freeze-drying process. experimental procedure involved depressurization technique in-vial measurements as well chamber pressure, which allowed analysis product batch, loaded in laboratory lyophilizator. average enlargement 93 58% incorporation nucleation step 6 wt% solutions, respectively. Consequently, primary...
Pool boiling experiments of water and ethanol-water binary mixtures were conducted on smooth laser textured stainless steel foils. High-speed IR thermography was used to measure transient temperature field during in order determine nucleation frequencies, site densities, bubble activation temperatures, wall-temperature distributions average superheats as well heat transfer coefficients. Saturated pool at atmospheric pressure over a flux range 5–250 kW m−2 for pure (1% 10% m/m). For both...
The newly developed computational fluid dynamics, transport, and chemical kinetics-based monolith catalyst dimensioning methodology consists of the following steps: (i) initial calculations, which generate some data, e.g., average inlet velocity used in (ii) dynamics (CFD) modelling, uses laminar flow interface transport diluted species while user has to provide kinetics reactions; (iii) model order reduction a modified version plug reactor linear pressure variation model; (iv) optimization...
The article presents the mathematical sequences describing circle packing densities in four different geometric configurations involving a hexagonal lattice based equal Euclidian plane. calculated take form of either polynomials or rational functions. If area is limited with circle, tend to decrease increasing number packed circles and converge values lower than {\pi}/(2\sqrt{3}). In cases areas by equilateral triangles hexagons increase are shown be preferred surface practical applications...
The screening of all non-radioactive metals without lanthanides for thermochemical hydrogen storage was performed based on physical chemistry calculations. thermodynamic data were collected from the NIST (National Institute Standards and Technology) public repository, which followed by calculations regarding change in enthalpy, entropy, Gibbs free energy equilibrium reaction temperature. results critically evaluated parameters, viable identified, their densities energy–enthalpy ratios...
A simplified physical model of a single bubble growth during nucleate pool boiling was developed. The able to correlate the experimentally observed data bubble’s time and its radius evolution with use appropriate input parameters. calculated values separated heat fluxes from heater wall, thermal boundary layer, bulk liquid gave us new insight into complex mechanisms process. layer found supply majority growing bubble. flux be close Zuber’s critical limit (890 kW/m2). This substantially...

In this study we investigate pool boiling of water at 0, 5, 10, and 20 K subcooling heat fluxes up to 250 kW/m2. The experiments are performed on smooth 6-μm titanium foil whereas a high-speed infrared video camera used measure spatio-temporal surface temperature variations visualize growing/collapsing vapor bubbles. Results show partial overlaying curves, which means that higher degree does not necessarily result in lower average wall temperature. all cases the bubble activation...
This paper investigates the latent heat flux during saturated pool boiling. The local is considered on a single nucleation site and has decreasing trend if empirical relation between bubble departure diameter frequency an exponent equal to or larger than one. If smaller one, starts increase with increasing radius. Empirical relations frequency, which enable decrease radius, were proposed. But some researchers of suggest, we take it be possible, that this could also have opposite nature....
