Thermal performance and pressure drop in a ceramic heat exchanger evaluated using CFD simulations
(2012)There is one potential demand for heat exchangers capable of supporting high temperatures, typically higher than 800 °C, for use in thermal power plants. These heat exchangers could be used in the implementation of EFGT ... -
Searching for strategies to reduce the mechanical demands of the sit-to-stand task with a muscle-actuated optimal control model
(2016)© 2016Background The sit-to-stand task, which involves rising unassisted from sitting on a chair to standing, is important in daily life. Many people with muscle weakness, reduced range of motion or loading-related pain ... -
Muscle force distribution of the lower limbs during walking in diabetic individuals with and without polyneuropathy
(2017)© 2017 The Author(s).Background: Muscle force estimation could advance the comprehension of the neuromuscular strategies that diabetic patients adopt to preserve walking ability, which guarantees their independence as they ... -
Thermodynamic study of an EFGT (externally fired gas turbine) cycle with one detailed model for the ceramic heat exchanger
(2012)The EFGT (externally fired gas turbine) cycle has been considered as an option to burn biomass in gas turbines. One key element on the implementation of one EFGT cycle is the high temperature heat exchanger (HTHE) necessary ... -
Heat transfer and pressure drop correlations for finned plate ceramic heat exchangers
(2015)© 2015 Elsevier Ltd.The use of ceramic materials is a good option to build heat exchangers for high temperature applications when cost is a concern. This work presents heat transfer and pressure drop correlations for one ... -
CAF—a simplified approach to calculate springback in Al 7050 alloys
(2017)© 2017, Springer-Verlag London.Aeronautical industries have looked for news fabrication processes to reduce the costs and the waste of the material during milling operations. One of these new processes is the creep age ... -
Effect of the hardening rules on the creep age forming prediction of 7050 aluminum alloy with experimental verification
(2018)© 2018, The Brazilian Society of Mechanical Sciences and Engineering.The creep age forming (CAF) has been used in the aerospace sector due to its attractive characteristics that allows producing a component with low residual ... -
Reverse strain-induced martensitic transformation of the ferrite to austenite in duplex stainless steels
(2016)© 2016, Springer Science+Business Media New York.The possibility of a reverse strain-induced martensitic transformation (RSIMT) of ferrite into austenite was evaluated in two duplex stainless steels (DSS) solution treated ... -
Predictive simulation of gait at low gravity reveals skipping as the preferred locomotion strategy
(2012)The investigation of gait strategies at low gravity environments gained momentum recently as manned missions to the Moon and to Mars are reconsidered. Although reports by astronauts of the Apollo missions indicate alternative ... -
Turbidity control on dissolved air flotation process using fuzzy logic
(2018)© IWA Publishing 2018. This study intends to explore fuzzy logic control on clean water turbidity process with dissolved air flotation (DAF). Three different strategies were tested to regulate clean water turbidity by ... -
