Dynamic performance of existing high-speed railway bridges under resonant conditions following a retrofit with fluid viscous dampers supported on clamped auxiliary beams
(Elsevier, 2014-02)
This contribution investigates the application of Passive Control techniques to reduce the severe transverse vibrations that railway bridges of moderate lengths may experience under resonant conditions. The proposed solution ...
Influence of the vehicle model on the prediction of the maximum bending response of simply-supported bridges under high-speed railway traffic
(Elsevier, 2014-08)
This investigation intends to contribute to the problem of train-bridge interaction in high-speed railway lines. For design purposes, most often a numerical model based on constant moving loads is used to reproduce the ...
Experimental Assessment of the Internal Heat Exchanger in Vapour Compression Systems With Low GWP Refrigerant R516A
(Elsevier, 2022)
Internal heat exchangers (IHX) are commonly used
to improve the energy performance of vapour
compression refrigeration cycles. However, the
magnitude of the improvement depends on the
refrigerant and operational ...
An experimental investigation on the characteristics of submerged horizontal gas jets in liquid ambient
(2014)
Gas injections into liquid are prevalent in the natural environment and are essential in industrial applications,
they can lead to complex flow. The flow structure and processes are essentially unsteady and turbulent.
