Conference Paper
Full-text available
Biomimicry is an emerging discipline that aims at finding more sustainable solutions to human challenges through nature’s emulation. Biomimicry is multi/interdisciplinary as it calls for the collaboration among diverse disciplines. Jargons, different perspectives and mindsets characterizing the various disciplines obstruct the knowledge sharing and...
Article
This work assesses the feasibility of the planar PIV technique to study the characteristics of a siloxane vapor D4. Titanium dioxide (TiO2) seeding particles were used to track the motion around a rotating disk in a low speed flow. Vector fields of natural convection (NC) and a superposition of NC and rotating flow were selected as exemplary cases....
Article
This paper documents the numerical investigation of the effects of non-uniform magnetic fields, i.e. magnetic-ribs, on a liquid–metal flowing through a two-dimensional channel. The magnetic ribs are physically represented by electric currents flowing underneath the channel walls. The Lorentz forces generated by the magnetic ribs alter the flow fiel...

Non-ideal compressible fluid dynamics (NICFD) are defined as compressible fluid flows occurring in the dense vapour, dense vapour-liquid equilibrium or supercritical thermodynamic region. This type of flow can occur in expanders of organic Rankine cycle power plants. In order to study NICFD, a Ludwieg tube-type facility has been designed and constr...
Article
Full-text available
This paper describes the commissioning of the flexible asymmetric shock tube (FAST), a novel Ludwieg tube-type facility designed and built at Delft University of Technology, together with the results of preliminary experiments. The FAST is conceived to measure the velocity of waves propagating in dense vapours of organic fluids, in the so-called no...
Article
The goal of this work is to provide a preliminary evaluation of a new high-potential concept for liquid cooling: an electrically conductive fluid can flow through channels, while magnetic fields promote flow-wall impinging, causing an effect analogous to channel ribs (turbulence promoters), but in principle the effect is controllable. In order to e...

The goal of this work is to evaluate a new high-potential concept for the convective heat transfer enhancement: electrically conductive fluid flows through channel walls and magnetic fields promote impinging, analogously to the ribs (turbulence promoters). DNS has been used to investigate the effects of non-uniform magnetic fields, i.e. magnetic ri...

Article
Infrared thermography has been employed to carry out a detailed convective heat transfer measurements at Re = 20,000 in a two-pass square channel both for the static case (absence of channel rotation) and for the rotating case (Ro = 0.3). At the same time, the main and secondary flow fields have been measured by means of particle image velocimetry...
Conference Paper
Full-text available
A new experimental technique is being developed to overcome the drawbacks exhibited by existing techniques used to perform temperature measurements in flow fields. It requires the insertion into the flow of a high porosity grid formed by a thin electrically conductive wire. By measuring the grid temperature distributions with an infrared (IR) camer...
Conference Paper
Full-text available
In order to optimize the emergency ventilation strategies put into operation during a tunnel fire, a better knowledge of the temperature and flow fields generated by a tunnel fire is required. Tests have been conducted in a model tunnel at ETH for different ventilation regimes indicating strong changes in the temperature field.
Article
Particle image velocimetry experiments have been carried out to obtain visualizations and measurements of the main and secondary flow fields in a square channel with a sharp “U” turn. Both the main and the secondary flow fields have been used to perform a 3D reconstruction of the mean flow and vortical fields in the turn region and in the outlet du...

Particle Image Velocimetry (PIV) experiments have been carried out to obtain visualizations and measurements of flow fields in a square channel with a 180° sharp turn. This paper is focused on the study of the secondary flow field in the turn region and, in order to study the influence of the rotation on the secondary flow field inside the channel,...

Particle image velocimetry (PIV) experiments have been carried out to obtain visualizations and meas-urements of flow fields in a square channel with a 180° sharp turn. In order to study the influence of the rotation on the flow field inside the channel, tests both in sta-tionary (absence of rotation) and rotating conditions have been performed. Th...
