“…The fluid flow in single or multiphase systems can be analyzed by various measurement techniques. Field and volume information can be achieved by imaging techniques using tracers, color changes as well as particle image velocimetry (PIV) , , laser‐induced fluorescence (LIF) or tomographic methods including combined solutions such as tomographic PIV , . Single point measurements are possible for example with hot‐wire anemometry, laser‐Doppler velocimetry (LDV) or ultrasound doppler velocimetry .…”

The experimental accessibility of disperse systems often is a critical factor when it comes to the development of modeling approaches that intend to converge towards an exact solution. Often, integral or pseudo‐homogeneous values are used to reduce the complexity of the system, but a detailed single particle or interface analysis is crucial to understand relevant effects that also affect the swarm behavior. A high number of experimental techniques with respective limitations and advantages is available to quantify these effects. In this work, an overview on measurement techniques for momentum, heat and mass transfer in particle swarms as well as for the particle size distribution and interface characterization is provided. The industrial applicability is addressed by pointing out the vicinity to the process and the costs of different measurement techniques.

“…These particles are characterized by a considerable value of the refractive index, as it is equal to 1.5. Due to the above characteristics, in many works [13,14,15], PSP particles are recommended for applications in systems including water phase flow in particular for the case of the complex stream trajectory. In order to obtain a constant water homogenization with seeding particles, an agitator was installed in the tank.…”

Abstract. This paper presents the results of an experimental study into flow through a tube bundle applied in shell-and-tube heat exchanger with segmental baffles built on an industrial scale. The reported research applied Digital Particle Image Velocimetry (PIV) technique. The study offered the determination of the velocity vector fields, which were subsequently used for identification and measurement of irregularity of flow distribution across the tube bundle. Differences in the intensity of local flow velocities in shell side were identified by velocity profiles analysis. Furthermore correlation between the map of local velocity and its location in particular tube rows was described. As a result, the three main regions of flow velocity variation throughout cross-section of the shell side were identified.

“…Zhang et al studied the turbulence kinetic energy dissipation rate and turbidity near the coast of East China Sea and concluded that the ocean mixing process has a mean turbulence kinetic energy dissipation rate of 5.7 ϫ 10 Ϫ5 W/kg (Zhang et al, 2016). Liu et al analyzed the anisotropy of the turbulence flow field via the turbulence kinetic energy and energy dissipation rate (Liu et al, 2016). The ocean turbulence leads to the dissipation and mixing of ocean populations; thus, the flow sensors used in ocean turbulence environment should have a low kinetic energy dissipation rate.…”

Purpose It is significant to know the real-time indexes about the turbulence flow of the ocean system, which has a deep influence on ocean productivity, distribution of the ocean populations and transmission of the ocean energy, especially the measurement of turbulence flow velocity. So, it is particularly urgent to provide a high-sensitivity, low-cost and reliable fluid flow sensor for industry and consumer product application. This paper aims to design a micro fluid flow sensor with a cross beam membrane structure. The designed sensor can detect the fluid flow velocity and has a low kinetic energy dissipation rate. Design/methodology/approach In this paper, a micro fluid flow sensor with a cross beam membrane structure is designed to measure the ocean turbulence flow velocity. The design, simulation, fabrication and measurement of the designed sensor are discussed. By testing the simply packaged sensor in the fluid flow and analyzing the experiments data, the results show that the designed sensor has favorable performance. Findings The paper describes the tests of the designed sensor, and the experimental results show that the designed sensor can measure the fluid flow velocity and has a sensitivity of 11.12 mV/V/(m/s)2 and a low kinetic energy dissipation rate in the range of 10-6-10-4 W/kg. Originality/value This paper provides a micro-electro-mechanical systems fluid flow sensor used to measure ocean turbulence flow velocity.
