Microstructural, mechanical and tribological characterization of Cu-Co-Ni-Be alloy processed via equal channel angular pressing
(Elsevier, 2021)
Effects of different processes including various combinations of equal channel angular pressing (ECAP) and aging on the microstructure, mechanical and tribological properties of the quadruple Cu-Co-Ni-Be alloy were ...
Performance assessment of solar chimney power plants with the impacts of divergent and convergent chimney geometry
(Oxford University Press, 2021)
Influence of area ratio (AR) on main performance parameters of solar chimney power plants (SCPPs) is investigated through a justified 3D axisymmetric CFD model. Geometric characteristics of Manzanares pilot plant (MPP) are ...
Effect of arc re-melting on microstructure, mechanical and tribological properties of commercial 390A alloy
(Elsevier, 2021)
To investigate the effect of the arc re-melting on the microstructure, mechanical and tribological properties of the 390A alloy, its ingot produced by the conventional induction melting method was subjected to the arc ...
Effect of boronizing on operating stability of steel AISI 304L under erosion impact of hard particles
(Springer, 2021)
The effect of solid boronizing at 950 degrees C for 2 and 4 h on the phase composition, microstructure, hardness and abrasive wear of steel AISI 304L is studied under the impact of a flow of hard particles. The boronized ...
Machine learning models to estimate the elastic modulus of weathered magmatic rocks
(Springer, 2021)
In recent years, several soft computing models have been proposed to estimate the elastic modulus of magmatic rocks. However, there are lacks in models that consider the different weathering degrees in determining the ...
Thermal energy storage performance of PCM/graphite matrix composite in a tube-in-shell geometry
(Elsevier, 2021)
Melting heat transfer performance and measuring energy storage efficiency via total melting time of PCM/ graphite matrix in a tube-in-shell for solar thermal energy storage and recovering waste heat applications is studied ...
Performance evaluation of solar chimney power plants with bayburt stone and basalt on the ground as natural energy storage material
(MDPI, 2022)
This research examines the effect of using Bayburt stone or basalt as an energy storage unit in SCPPs. The effect of using low-cost materials on the system performance is evaluated. Based on the Manzanares pilot plant ...
Combined influence of artificial nucleation site and expanding cross section on flow boiling performance of micro pin fins
(Elsevier, 2022)
Present paper experimentally studies combined influence of artificial nucleation sites and expanding cross section on saturated flow boiling performance of heat sinks with micro pin fins. Thermal and visualization-based ...
Heat storage and release performance of cascade phase change units for solar heating in a severe cold region of China
(MDPI, 2022)
The heat storage and release performance of cascade phase change units are investigated numerically for users in Inner Mongolia's severe cold region. Three schemes of phase change material combinations are thoroughly tested. ...
UV coated acrylics as a substitute for generic glazing in buildings of Indian climatic conditions: Prospective for energy savings, CO2 abatement, and visual acceptability
(Elsevier, 2022)
The generic clear glass used in the existing buildings has the limitations such as high heat gain/loss, glare, and poor thermal performance. Substitution for the existing building conventional glazing systems should be ...
