The (Ba,Ca)(Zr,Ti)O3 ceramic system has received special attention in recent years because it may lead to promising lead-free piezoceramics. However, the stability of the functional properties of these materials is an ...

Two-phase flows are encountered in a wide range of applications both on-ground and in space. The dynamics of such flows in the absence of gravity is completely different from that in normal gravity due to the absence of ...

An experimental setup for the study of bubbly jets collision in microgravity has been designed. On ground preliminary results are presented in order to be compared with those obtained in a near future in low gravity ...

Ultrasonic transducer design is focused to maximize performance in specific applications, usually leading to a complex design and expensive construction and assembly. With the aim to overcome ...

Bubble detachment, rise, and bouncing upon impact with a free surface is studied experimentally in variable gravity conditions. Previous investigations focused on the effects of fluid properties such as ...

Grain-size effect on functional properties of piezoceramics is nowadays an important topic due to the potential applications of these materials at the submicron scale. In this context, we explore the effect of the grain ...

We present a new experimental setup for the study of bubble coalescence and bubble jet interactions in microgravity conditions [1].Test section consists of a cavity full of liquid containing two bubble injectors whose ...

We present an experimental setup for the study of the effects of controlled harmonic vibrations applied on multiphase systems in microgravity. This setup was recently launched onboard an ESA/DLR/SNSB Mini-Texus rocket with ...

An experimental setup for the study of droplet collisions in a drop tower is presented.
