Hydraulics & Hydrodynamics

Hydrodynamics is the study of liquids in motion. Examples of applications include determining the mass flow rate of petroleum through pipelines, measuring flows around bridge pylons and offshore rigs, ship hull design, optimizing propulsion efficiency, predicting weather patterns and wave dynamics, and measuring liquid metal flows. Benefits include decreased fuel consumption, reduced drag on structures, minimizing noise and vibration, and mitigating unwanted effects, like fouling.

Hydraulics deals with the mechanical properties of liquids, focusing on the engineering uses of fluid properties. Some industrial hydraulic applications are pipe flow, dam design, pumps, turbines, hydropower, computational fluid dynamics, flow measurement, river channel behavior and erosion. Other applications include heart-valve functions, blood flows, wave dynamics, sedimentation transport, coastal engineering and river hydrology.

PIV measurements during the dolphin kick of a human swimmer

Only a few methods to visualize and quantify flow have been so far applied to human swimming. They range from the observation of natural or injected air bubbles to the orientation of tufts a[…]
