Project description
Shedding new light on the fluid mechanics of sudden movements
When an object changes speed, for example a racing car making a sharp turn, the flows which surround it change. Measuring these impulsive flows is more complex than measuring flows where the speed is constant. Existing fluid mechanics theory and facilities overlook accelerations in the measuring process. This makes it difficult to predict flows in the event of unexpected movements. The EU-funded ImpulsiveFlows project plans to build an entirely new fluid mechanics facility that will be able to simulate complex movements using a robotic arm. This robotic arm will move and rotate various objects in a water-filled tank along certain trajectories with known acceleration and rotation. The fluid flow around objects will be measured using tomographic particle image velocimetry.
Objective
My goal is to investigate impulsive flows that occur both in nature and technological applications, where fluid is accelerated due to sudden motion of an object or boundary, which leads to an additional instationary drag or lift forces. This project will shed new light on the understanding of the fundamental properties and flow physics of these impulsive flows. Theoretical concepts that are used today, do not go much beyond those laid down almost 100 years ago. With todays level of technology and experimental tools I will be able to break new ground in the understanding of these flow phenomena that are very challenging both experimentally and numerically. First, a novel-concept flow facility will be built, based on a high performance robotic arm; this robot arm can move and rotate various objects in a water-filled tank along prescribed trajectories with known acceleration and rotation. The fluid motion is measured using tomographic particle image velocimetry (PIV), of which the measurement volume can move along with the objects using auxiliary robot arms. New PIV approaches will be developed that measure fluid acceleration varied within the short times of these impulsive motions. Then a systematic investigation is performed on various impulsive flows where the rate of acceleration and rotation rate can be varied, in order to find new
and improved relationships between the measured hydrodynamic force histories and relevant flow quantities, such as velocity, acceleration, and rotation rate, and the time scales at which these phenomena occur. These will represent real-life impulsive flows. Experimental approaches and results will be used to validate numerical methods. The results of this investigation will fill gaps in our knowledge of impulsive flows, and give more accurate estimates of hydrodynamic forces. This will improve the prediction of structural loads and reduce failure and discomfort, with impact on aeronautics, wind energy, maritime and offshore technology.
