An experimental and theoretical analysis of vapor-to-liquid phase change on microstructured surfaces
(Elsevier, 2020-09)
In this work, an experimental and a theoretical study was carried out on condensation heat transfer on vertically aligned bare unstructured, micro V-grooved and square-grooved copper substrates. During the experiments, ...
Investigation of the effect of particle stability on the transport properties and thermal behavior of ethylene glycol-water/SiO2 binary nanofluids
(IOP Publishing, 2020-04-09)
Nanofluids (Nfs) are considered as an effective working media in different thermal processes. Over the years, much attention has been paid to the problem of nanoparticle stability in base fluids in an unconfined area of ...
An integrated homogenization–based topology optimization via RBF mapping strategies for additively manufactured FGLS and its application to bandgap structures
(Springer Nature, 2020)
The manufacturing of lattice structures has been greatly facilitated thanks to the advances in additive manufacturing. Functionally graded lattice (FGL) structures, a major class of such structures, developed using topology ...
Simultaneous improvement in strength and ductility of severely deformed niobium alloy
(Elsevier, 2020-11-15)
The present study is on the improved monotonic response of a severely deformed niobium-based alloy. Nb-1Zr alloy was processed at room temperature using equal channel angular extrusion and cold rolling. After 16 passes, a ...
Modeling, transient simulations and parametric studies of parabolic trough collectors with thermal energy storage
(Elsevier, 2020-03-15)
For investigating the system response of parabolic trough collector heat generating system, a plant with parabolic trough collector field and two-tank molten salt thermal energy storage model with component-level control ...
Effect of polymer coating on vapor condensation heat transfer
(ASME, 2020-04-01)
Condensation heat transfer coefficients (HTCs) are rather low compared to thin film evaporation. Therefore, it can be a limiting factor for designing heat transfer equipment. In this work, heat transfer characteristics of ...
Fatigue characteristics of continuous welded rails and the effect of residual stress on fatigue-ratchetting interaction
(Taylor & Francis, 2020-03-16)
The importance of ratchetting-fatigue interaction is garnering interest due to complex failure mechanism of rail welds under cyclic loading. The objective of this paper is to investigate the fatigue characteristics of ...
Fracture behavior of ultrafine-grained titanium under tension at elevated temperatures
(ASME, 2020-10-01)
This investigation focused on the deformation response and microstructural changes of severely deformed titanium during post-severe plastic deformation tension, at temperatures of 300–600 °C and at strain rates of 0.001–0.1 ...
Segregated modeling of continuous heat treatment furnaces
(Elsevier, 2020-07)
Heat treatment processes have a major impact on the mechanical and structural properties of the end products. Accurate control of the material temperatures during the heating and cooling regimes is very crucial for the ...
Enhanced thermal performance of high flux led systems with two-phase immersion cooling
(IEEE, 2020)
Considering significant worldwide use of electricity for general lighting, the implementation of energy efficient technologies is highlighted in many platforms with the use of light emitting diodes (LEDs). Because of its ...
