Summary

Recent advances in nanotechnology and piezoelectric technology have led to the development of sophisticated materials that may be used in a variety of applications. Studies of material structure-sensitive characteristics and nanotechnology methods are presently ongoing. There has been a lot of interest in novel materials for engineering applications with high accuracy, longevity, and enhanced capabilities to work with high temperature and pressure ranges, which show characteristics defined by the use of materials and composites with improved properties, creating new possibilities in the study of various physical processes, especially signal transmission.

In academia and industry, research on thermal management systems and energy usage that are more efficient and cost-effective isn't expanding as fast as it should. Due to the fact that energy and thermal management are closely connected, this Special Issue combines the two topics into one publication. A specific emphasis is placed on the function of different forms of controls, notably dynamics controls, in increasing the thermal processes and fluid flow conditions in high-speed and aerospace vehicles, etc. Thermal management systems are studied using numeric simulation approaches and experimental research. Energy use and the environment are included in the scope of this Special Issue. In these domains, the application of alternative modelling approaches utilizing machine learning techniques is relatively new and expanding rapidly, and so comes within the scope of this Special Issue.

This special issue calls papers on experimental investigations, modelling, and simulation of a wide variety of materials, energy, and fluid dynamics.

    Abstract In the present study, the base pressure variations induced by the presence of a cavity, known to have a strong influence of the behaviour of supersonic projectiles, are investigated through numerical solution of the balance equations for mass, momentum, and energy. An area ratio of four is considered and numerical simulations are carried out at Mach M = 1.2, 1.4, 1.6, and 1.8 assuming no cavity or cavity locations 0.5D, 1D, 1.5D, and 2D. The inlet pressure of the nozzle is considered as a flow variable. The Taguchi method is also used, and the considered cases are then analyzed using… More >

    Computation of Stiffness and Damping Derivatives of an Ogive in a Limiting Case of Mach Number and Specific Heat Ratio

    Abstract This work aims to compute stability derivatives in the Newtonian limit in pitch when the Mach number tends to infinity. In such conditions, these stability derivatives depend on the Ogive’s shape and not the Mach number. Generally, the Mach number independence principle becomes effective from M = 10 and above. The Ogive nose is obtained through a circular arc on the cone surface. Accordingly, the following arc slopes are considered λ = 5, 10, 15, −5, −10, and −15. It is found that the stability derivatives decrease due to the growth in λ from 5 to 15 and vice versa.… More >

    Passive Control of Base Pressure in a Converging-Diverging Nozzle with Area Ratio 2.56 at Mach 1.8

    Nur Husnina Muhamad Zuraidi, Sher Afghan Khan, Abdul Aabid, Muneer Baig, Istiyaq Mudassir Shaiq
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.3, pp. 807-829, 2023, DOI:10.32604/fdmp.2023.023246
    (This article belongs to this Special Issue: Materials, Energy, and Fluid Dynamics)
    Abstract In this study, a duct is considered and special attention is paid to a passive method for the control of the base pressure relying on the use of a cavity with a variable aspect ratio. The Mach number considered is 1.8, and the area ratio of the duct is 2.56. In particular, two cavities are examined, their sizes being 3:3 and 6:3. The used L/D spans the interval 1–10 while the NPRs (nozzle pressure ratio) range from 2 to 9. The results show that the control becomes effective once the nozzles are correctly expanded or under-expanded. The pressure contours at… More >

    A Systematic Review of Thermoelectric Peltier Devices: Applications and Limitations

    M. K. Shilpa, Md Abdul Raheman, Abdul Aabid, Muneer Baig, R. K. Veeresha, Nagesh Kudva
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.1, pp. 187-206, 2023, DOI:10.32604/fdmp.2022.020351

    Abstract Conventional refrigeration processes release ammonia and freon into the atmosphere, which results in global warming. These problems may be overcome by using thermoelectric modules because of the absence of coolants or refrigerants in these systems. However, the cooling performances of such modules are relatively small in comparison to those of conventional refrigerators. In this paper, the working principles of thermoelectric modules are discussed together with a review of different relevant aspects, namely: the thermoelectric materials, and their mechanical properties used to build thermoelectric devices, different types of thermoelectric devices available on the market, mathematical modeling of thermoelectric materials, and various… More >

    Numerical Analysis of a Microjet-Based Method for Active Flow Control in Convergent-Divergent Nozzles with a Sudden Expansion

    Abdul Aabid, Sher Afghan Khan, Muneer Baig
    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.6, pp. 1877-1900, 2022, DOI:10.32604/fdmp.2022.021860
    (This article belongs to this Special Issue: Materials, Energy, and Fluid Dynamics)
    Abstract A method based on microjets is implemented to control the flow properties in a convergent-divergent nozzle undergoing a sudden expansion. Three different variants of this active control technique are explored numerically by means of a finite-volume method for compressible fluid flow: with the first one, the control is implemented at the base, with the second at the wall, while the third one may be regarded as a combination of these. When jets are over-expanded, the control is not very effective. However, when a favourable pressure gradient is established in the nozzle, the control becomes effective, leading to an increase in… More >

    Wenbin Luo, Youmin Wang, Yuting Yan, Yifang Shi, Zhendong Zhang
    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.3, pp. 789-813, 2022, DOI:10.32604/fdmp.2022.019691
    (This article belongs to this Special Issue: Materials, Energy, and Fluid Dynamics)
    Abstract In order to determine the optimal structural parameters of a plastic centrifugal pump in the framework of an orthogonal-experiment approach, a numerical study of the related flow field has been performed using CFX. The thickness S, outlet angle β2, inlet angle β1, wrap angle, and inlet diameter D1 of the splitter blades have been considered as the variable factors, using the shaft power and efficiency of the pump as evaluation indices. Through a parametric analysis, the relative importance of the influence of each structural parameter on each evaluation index has been obtained, leading to the following combinations: β1 19°, β2… More >
