Numerical analysis of different mass transfer models for falling film absorbers
(Elsevier Ltd., 2022)
Different methodologies have been used in the literature to determine the absorbed vapour mass flux in falling film absorbers. So far, however, there has been little discussion about the impact of different ap- proaches ...
Experimental and numerical dynamic analysis of press-formeda viscoelastic sanwich structures
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2011)
This dissertation presents the experimental and numerical dynamic analysis of press-formed viscoelastic sandwich structures composed by two thin metallic face layers and a constrained viscoelastic film. Such structures can ...
Experimental uncertainty decompositions of aerodynamic coefficients affected by operative condition variations
(Elsevier Ltd., 2020)
A twofold analysis is performed on an experimental set-up comprising a low-Reynolds wind tunnel, with the aim of quantifying the effect of measurand uncertainties and operative condition variations in the lift and drag ...
Assessing the statistical validity of momentum-deficit-based measurements in turbulent configurations
(Elsevier Ltd., 2021)
An application-agnostic procedure is outlined for checking the validity of momentum-deficit-based drag measurements performed under different turbulent conditions in a wind tunnel. The approach defines a two-step methodology: ...
Theoretical Concepts for Describing a Replication-levels-based Uncertainty Analysis Approach
(International Frequency Sensor Association IFSA, 2021)
Analysis of One-Way and Two-Way FSI Approaches to Characterise the Flow Regime and the Mechanical Behaviour during Closing Manoeuvring Operation of a Butterfly Valve
(World Academy of Science, Engineering and Technology, 2018)
Butterfly valves are widely used industrial piping components as on-off and flow controlling devices. The main challenge in the design process of this type of valves is the correct dimensioning to ensure ...
Contact angle measurement for LiBr aqueous solutions on different surface materials used in absorption systems
(Elsevier Ltd., 2018)
Wetting surface is a very important issue for the design of absorption applications and heat exchangers. The contact angle is deemed essential in wettability studies; However, LiBr aqueous solution contact angle studies ...
Numerical methodology based on fluid-structure interaction to predict the residual stress distribution in glass tempering considering non-uniform cooling
(Elsevier, 2022)
In this paper a novel numerical methodology for calculating non-uniform residual stress distributions during the glass tempering process is presented. Tempering techniques lead to non-uniform heat transfer rates causing ...
