“…Once the air flow is fully developed, the inlet velocity field stabilizes, and the crystal deformation approaches a steady‐state value of 0.057 mm. Similar trends in beam tip deformations have been reported for varying air flows [48, 49] …”

One of the typical haptic elements are natural hairy structures that animals and plants rely on for feedback. Although these hair sensors are an admirable inspiration, the development of active flow sensing components having low elastic moduli and high aspect ratios remains a challenge. Here, we report a new sensing approach based on a flexible, thin and optically transmissive organic crystal of high aspect ratio, which is stamped with fluorescent dye for tracking. When subjected to gas flow and exposed to laser, the crystal bends due to exerted pressure and acts as an optical flow (hair) sensor with low detection limit ( � 1.578 m s À 1 ) and fast response time ( � 2.70 s). The airflow-induced crystal deformation and flow dynamics response are modelled by finite element analysis. Due to having a simple design and being lightweight and mechanically robust this prototypical crystal hair-like sensor opens prospects for a new class of sensing devices ranging from wearable electronics to aeronautics.

“…At the same time, the acoustic efficiency has been increased up to 3 % by using tandem. Tabatabaei et al 15 also studied the FSI in three dimensions for a rod. The researchers proved that the deformation of the rod increased by up to 90% between 0.25 and 0.35 m/s.…”

This research aims to analyze and compare the flutter of turbine compressor blades from experimental, numerical, and fluid structure interaction (FSI) derived data. The results proved that the FSI solution results are closer to the experimental results. A reduced velocity parameter of 5 can be regarded as the flutter boundary in the bending flutter. Additionally, the incidence angle parameter equal to 1.5 can be characterized as the torsional flutter boundary. Tandem leads to strengthening the load applied on the compressor blades, reducing the number of compressor stages, and ultimately reducing the weight of the engine. Adding tandem to the rotor increases the vibration bending frequency by a factor of 2. Increasing the compressor velocity caused the FSI vibration frequency to be close to the experimental results. It was found that the vibration range of the main rotor is greater than that of the tandem. The vibration of the rotor and the tandem is damped for approximately 0.1 s to reach a constant frequency.

“…This is accomplished by using a variety of software with varying degrees of efficiency for edge computing and cloud manufacturing applications for technological process monitoring based on digital twins [5]. Accordingly, it was possible to simulate a flexible structure dynamically using MATLAB [6] and other software like COMSOL [7,8], ANSYS [9,10] and Fluent [11]. Obtaining high heat transfer rates through various enhancement techniques can lead to substantial energy savings.…”

In energy applications, convection plays a dominant role in the transport of energy for the proper design in order to achieve higher heat transfer rates. Where the fluid motion is simply induced by density gradients. This study is concerned with transient natural convection in an isosceles-superimposed triangular enclosure. The inclination of the inclined partitions walls was θ =45°. Critical Rayleigh numbers have been obtained: Ra=106, especially for the fluid crushed between the two triangles where we can visualize the critical convection transaction between the air and water. The results in quantitative measurement of average Nusselt number change and qualitative visualization of streamline and isotherms are examined. The air and water streamlines and the temperature fields were obtained for the Rayleigh numbers 103 ≤ Ra ≤ 108 for both cases studied. Besides, the highest heat transfer performance is observed during the natural convection case of the water fluid, and the lowest heat is transferred when the fluid is dilatant. The triangular shape can greatly enhance the heat transfer from the bottom to the top at first in a smooth and harmonious manner, and then it turns into a more complex and disorderly shape when the water reaches high temperatures.
