Thermomechanical behavior of bio-fiber composite thermal insulation panels
(Elsevier Science Sa, Lausanne, 2020)
The thermomechanical properties of the bio-fiber composite, as material for the production of thermal insulation panels, were evaluated. The observed mixtures were composed of Miscanthus x giganteus bio-fibers, mineral ...
Application of modified Kalina cycle in biomass chp plants
(Wiley, Hoboken, 2020)
This paper presents alternatives to Kalina cycles typically used in place of the organic Rankine cycle in biomass power plants. Overviews of both Rankine and Kalina cycles are given alongside the possibilities of using ...
Investigation of the tribological performance of ionic liquids in non-conformal EHL contacts under electric field activation
(Springer, New York, 2020)
Real-time external alteration of the internal properties of lubricants is highly desirable in all mechanical systems. However, fabricating a suitable and effective smart lubricant is a long-lasting experimental process. ...
Closed-form solution for the free axial-bending vibration problem of structures composed of rigid bodies and elastic beam segments
(Elsevier Science Inc, New York, 2020)
In this paper, the coupled axial-bending vibration of planar serial frame structures composed of rigid bodies and Euler-Bernoulli beam segments is considered. The corresponding mode orthogonality conditions for this kind ...
Mathematical modelling and optimisation of lignite and wheat straw co-combustion in 350 MWe boiler furnace
(Elsevier Sci Ltd, Oxford, 2020)
In this paper pulverised lignite-fired 350 MWe boiler furnace is selected for numerical simulations performed by using in-house developed computer code to deepen understanding of complex processes during direct co-firing ...
Upgrade of the thermal power plant flexibility by the steam accumulator
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Thermal power plants are forced to operate under frequent load changes in energy systems with increased share of solar and wind power plants. These load changes increase thermal power plant aging and reduce their efficiency. ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, Amsterdam, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
Fixed Points on Covariant and Contravariant Maps with an Application
(MDPI, 2022)
Fixed-point results on covariant maps and contravariant maps in a (Formula presented.) -algebra-valued bipolar metric space are proved. Our results generalize and extend some recently obtained results in the existing ...
Averaged cubature schemes on the real positive semiaxis
(Springer, 2022)
Stratified cubature rules are proposed to approximate double integrals defined on the real positive semiaxis. In particular, anti-Gauss cubature formulae are introduced and averaged cubature schemes are developed. Some of ...
A partitioned solution approach for the fluid-structure interaction of thin-walled structures and high-Reynolds number flows using RANS and hybrid RANS-LES turbulence models
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2021)
In this work the partitioned solution approach for the fluid-structure interaction (FSI) of thin-walled structures and high-Reynolds number (Re) flows modeled using Reynolds-Averaged Navier-Stokes (RANS) and hybrid ...
