Effects of Annular-finned Tube Deformation on Thermal Stresses in a Heat Exchanger

open access: yesNigerian Journal of Technological Development, 2022
Nowadays, along with the developments in the industry, many machines and structures are exposed to very high-temperature environments, which has caused various types of thermal load in them.

Spatio-Thermal Variability and Behaviour as Bio-Thermal Indicators of Heat Stress in Dairy Cows in a Compost Barn: A Case Study

open access: yesAnimals, 2021
The spatial variability and behavioural aspects of compost-bedded pack barns remain unknown in subtropical regions. In this study, we investigated whether spatial variability occurs in the thermal environment of a compost barn and how the behaviour of ...

Mathematical modeling and simulation of porosity on thermomechanical properties of UHTCs under hypersonic conditions

open access: yesInternational Journal of Ceramic Engineering & Science, 2023
Ultrahigh temperature ceramics (UHTCs) were analyzed for their suitability in hypersonic flight conditions using balanced heat equations, transport equation, and finite element modeling technique. Mathematical model was derived on the assumption that the

Thermal Analysis of Si/GaAs Bonding Wafers and Mitigation Strategies of the Bonding Stresses

open access: yesAdvances in Materials Science and Engineering, 2017
In order to effectively reduce the thermal stresses of Si/GaAs bonding wafers during their annealing process, first of all, based on E. Suhir’s bimaterial thermal stress theory, the thermal stresses in the wafer bonding interfaces are analyzed and the ...

On the Relevance of the Thermal Scalar [PDF]

open access: yes, 2014
We discuss near-Hagedorn string thermodynamics in general spacetimes using the formalism of the thermal scalar. Building upon earlier work by Horowitz and Polchinski, we relate several properties of the thermal scalar field theory (i.e. the stress tensor

The spatial and temporal evolution of thermal stress after granite emplacement and its influencing factors

open access: yesDizhi lixue xuebao
Objective  Granitic magmas are genetically associated with magmatic-hydrothermal deposits and oil and gas reservoirs. The emplacement of granitic magmas into cooler rocks produced thermal anomaly and thermal stress, yet systematic studies on the spatial ...
