Methods for flow visualization have been decisive for the historical development of fluid
mechanics. In recent years, technological advances in cameras, lasers, and other devices …

Aquatic robotics is making a critical transition to adapt and inspire more efficient systems
from nature. The result is the abandonment of inefficient propeller-based locomotion for a …

In this study, we experimentally investigated the flow field characteristics in the complex
geometry of a tightly packed 61-rod bundle with wire spacers by employing matched-index …

Particle velocimetry is a non-intrusive optical measurement method whereby global velocity
fields can be obtained in either two-or three-dimensions through time by inferring fluid …

The calibration of a multi-camera system is a crucial step of volumetric flow measurements
with photogrammetric methods. Conventional calibration methods are based on recording …

Soil splash is the first step of water erosion. There are many methods for splash
investigations however the use of high-speed cameras is becoming increasingly popular …

In the beginning of the 20th century, Nikola Tesla invented, built and patented the Tesla
turbine. Driven by a pressure difference, the kinetic energy of fluids or gases is converted to …

This chapter initially provides the reader with an extensive survey of the many methods
available to measure the flow velocity in three-dimensional problems. Afterwards, the …

The inward flow between two parallel, co-rotating disks undergoes a thorough examination
by analytical, experimental and numerical means. The analytical approach utilizes the …

When acquiring quantitative data using cameras, calibration is required to establish the
mapping relation between the image space and physical space. Calibration targets with …
