An experimental study on the heat transfer and wettability characteristics of micro-structured surfaces during water vapor condensation under different pressure conditions
(Elsevier Ltd, 2021)
In this study, condensation characteristics of water vapor on micro-structured surfaces at different pressures and subcooling temperature has been investigated experimentally. This work represents a basic study in order ...
Effects of alumina (Al2O3) addition on the cell structure and mechanical properties of 6061 foams
(Cambridge Univ Press, 2013)
In this study, a powder blend representing 6061 Al-alloy was first mixed with Al2O3 ceramic particles and then foamed by using the powder compact melting method. 6061-Al2O3 foams and control specimens 6061 foams (without ...
Gas-driven thin liquid films: effect of interfacial shear on the film waviness and convective heat transfer
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2019)
This study is aimed at experimental investigation of hydrodynamics and convective heat transfer in gravity and gas-driven thin liquid wall films. The liquid film has been annularly applied on a vertically aligned heated ...
Calibration-free extraction of constitutive parameters of magnetically coupled anisotropic metamaterials using waveguide measurements
(Amer Inst Physics, 2017)
A calibration-free method for extraction of electromagnetic properties of magnetically coupled anisotropic biaxial metamaterial (MM) slabs from waveguide measurements is proposed. It relies on three measurement steps (thru, ...
Stress, strain and strain-rate cemented carbide properties determined with a fem-supported evaluation of impact test imprints
(Elsevier Sci Ltd, 2021)
Cemented carbide materials are key in tool manufacturing, nowadays widely used in cutting, forming and other manufacturing processes. Commonly applied methods for obtaining their strain-rate dependent material properties ...
Stiffening of biopolymer aerogel networks upon wetting: a model-based study
(Elsevier, 2020)
The mechanism behind the stiffening effect observed in the stress-strain response of alginate-starch aerogels upon being exposed to wetting is investigated in this paper, via a physically motivated model approach. A network ...
Evaluation of NaOH pre-treatment on the corrosion behavior and surface characteristics of hydroxyapatite coated NiTi alloy
(Springer Heidelberg, 2020)
Successful short-term implementation of nickel-titanium (NiTi) alloys as implants has been a motivation for the development of long-term applications. However, rendering these as safe implant materials is challenging. The ...
Core-shell PVA/gelatin nanofibrous scaffolds using co-solvent, aqueous electrospinning: toward a green approach
(Wiley, 2018)
Electrospinning (ES) of gelatin often requires cytotoxic organic solvents or acidic environments, which deteriorate cell recognition sites. In this study, aqueous, non-toxic, co-solvent ES was performed to obtain core-shell ...
Effect of polymer coating on vapor condensation heat transfer
(Asme, 2020)
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 ...
Mechanical characterization of B4C reinforced aluminum matrix composites produced by squeeze casting
(Cambridge Univ Press, 2017)
Boron carbide (B4C) ceramic particles were used as reinforcement material to produce aluminum (Al) matrix composites by squeeze casting method. Four different B4C contents as 0, 3, 5, and 10 wt%, and three different squeeze ...
