Harmonization of new wind turbine rotor blades development process: A review
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this paper the harmonization of new wind turbine rotor blades development is given as well as the analysis of behavior by verification testing for a wind turbine rotor blade of composite materials. The design, fabrication, ...
Dynamics of steam accumulation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Steam accumulators are applied as buffers between steam generators and consumers in cases of different steam production and consumption rates. The steam accumulator is filled with water and steam and it operates with a ...
Analysis of fouling factor in district heating heat exchangers with parallel helical tube coils
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
This paper presents the results of measurements of thermal performance of 8 heat exchangers with parallel helical coils. Measurements were conducted in substations in 2 district heating systems in Serbia: Belgrade and ...
Structural, mechanical and tribological properties of A356 aluminium alloy reinforced with Al2O3, SiC and SiC plus graphite particles
(Elsevier Science Sa, Lausanne, 2010)
Particulate composites with A356 aluminium alloy as a matrix were produced by compocasting process using ceramic particles (Al2O3, SiC) and graphite particles. The matrix alloy and the composites were thermally processed ...
A fuzzy model for an increase in locomotive traction force
(Vilnius Gediminas Tech Univ, Vilnius, 2010)
This paper deals with the process of traction force realization described by a suitable mechanical model and is pointed to the adhesion phenomenon as a physical one, i.e. is a suitable factor that the value of traction ...
Energy-saving estimation model for hypermarket HVAC systems applications
(Elsevier Science Sa, Lausanne, 2011)
Energy saving estimation model (ESEM) use normal distribution (Gaussian) probability theory to predict potential savings for previously determined system improvements. Those improvements are low/high cost investments based ...
Bifurcation control of a generalized VDP system driven by color-noise excitation via FOPID controller
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Fractional-order PID (FOPID) controller, as the results of recent development of fractional calculus, is becoming wide-used in many deterministic dynamical systems, but not in stochastic dynamical systems. This paper ...
A numerical investigation of the refrigerant maldistribution from a header towards parallel channels in an evaporator of automotive air conditioning system
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Evaporators in automotive air conditioning are designed as compact heat exchangers with the aim to cool outside air for the widest possible range of weather conditions. Under low operating loads a non-uniformity of the ...
Groundwater heat pump selection for high temperature heating retrofit
(Elsevier Science Sa, Lausanne, 2012)
Retrofitting of fossil fuel powered hot water radiator heating systems of the existing buildings by groundwater heat pumps can provide significant energy savings followed by economic and environmental benefits. The paper ...
Common fixed point under contractive condition of Ciric's type on cone metric type spaces
(Springer International Publishing Ag, Cham, 2012)
The purpose of this article is to generalize common fixed point theorems under contractive condition of A dagger iriA double dagger's type on a cone metric type space. We give basic facts about cone metric type spaces, and ...
