Achieving sustainable work of the heat pump with the support of an underground water tank and solar collectors
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with the methodology of sizing a sustainable heating-cooling system, which consists of a heat pump, thermo-solar collectors and underground water tank, as a seasonal thermal energy storage. The methodology ...
Numerical study of pulverized coal-fired utility boiler over a wide range of operating conditions for in-furnace SO2/NOx reduction
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Important tasks during pulverized coal-fired utility boiler exploitation are efficient utilization of variable quality fuels, operation in a wide range of loads and emission reduction of pollutants, like oxides of nitrogen ...
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 ...

Structural investigation of mechanically activated ZnO powder
(Elsevier Science Sa, Lausanne, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...
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 ...
Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Elsevier Sci Ltd, Oxford, 2007)
Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since ...
Model-free and model-based analysis of thermo-oxidative response of wolfberries: A new developed mechanistic scheme
(Elsevier Sci Ltd, Oxford, 2021)
Thermally accelerated oxidative degradation of wolfberry pulp was kinetically monitored using model-free and model-based approaches. Kinetic calculations were performed based on simultaneous thermal analysis measurements ...
