Summary

Many countries have stated their goals of being carbon neutrality. The widespread use of low-carbon energy and energy conservation technologies in thermodynamic systems is one of the most important ways to achieve carbon neutrality. This involves many disciplines of science and engineering, such as energy and power engineering, mechanical engineering, material science, chemical and petroleum engineering, aerospace engineering, control science and engineering, architecture and civil engineering, electrical engineering, environmental science and engineering.

    Numerical Analysis of Flow-Induced Vibration and Noise Generation in a Variable Cross-Section Channel

    Youhao Wang, Chuntian Zhe, Chang Guo, Jinpeng Li, Jinheng Li, Shen Cheng, Zitian Wu, Suoying He, Ming Gao
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.12, pp. 2965-2980, 2023, DOI:10.32604/fdmp.2023.029292

    Abstract Flow channels with a variable cross-section are important components of piping system and are widely used in various fields of engineering. Using a finite element method and modal analysis theory, flow-induced noise, mode shapes, and structure-borne noise in such systems are investigated in this study. The results demonstrate that the maximum displacement and equivalent stress are located in the part with variable cross-sectional area. The average excitation force on the flow channel wall increases with the flow velocity. The maximum excitation force occurs in the range of 0–20 Hz, and then it decreases gradually in More >

    Experimental Study on the Thermal Performances of a Tube-Type Indirect Evaporative Cooler

    Tiezhu Sun, Huan Sun, Tingzheng Tang, Yongcheng Yan, Peixuan Li
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.10, pp. 2519-2531, 2023, DOI:10.32604/fdmp.2023.027118

    Abstract The so-called indirect evaporative cooling technology is widely used in air conditioning applications. The thermal characterization of tube-type indirect evaporative coolers, however, still presents challenges which need to be addressed to make this technology more reliable and easy to implement. This experimental study deals with the performances of a tube-type indirect evaporative cooler based on an aluminum tube with a 10 mm diameter. In particular, the required tests were carried out considering a range of dry-bulb temperatures between 16°C and 18°C and a temperature difference between the wet-bulb and dry-bulb temperature of 2°C∼4°C. The integrated convective More >

    Stability and Thermal Property Optimization of Propylene Glycol-Based MWCNT Nanofluids

    Xi Wang, Shan Qing, Zhumei Luo, Yiqin Liu, Zichang Shi, Jiachen Li
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.9, pp. 2399-2416, 2023, DOI:10.32604/fdmp.2023.028024
    (This article belongs to the Special Issue: Advances in Thermodynamic System and Energy Conservation Technology)
    Abstract Propylene glycol-based MWCNT (multi-walled carbon nanotubes) nanofluids were prepared in the framework of a two-step method and by using a suitable PVP (polyvinyl pyrrolidone) dispersant. The BBD (Box-Behnken design) model was exploited to analyze 17 sets of experiments and examine the sensitivity of the absorbance to three parameters, namely the concentration of MWCNT, the SN ratio (mass ratio of carbon nanotubes to surfactants) and the sonication time. The results have revealed that, while the SN ratio and concentration of MWCNT have a strong effect on the absorbance, the influence of the sonication time is less… More >

    Abstract A review is conducted about the application of the evaporative cooling technology in thermal power plants. Different case studies are considered, namely, evaporative air conditioners, evaporative cooling in direct air-cooled systems, gas turbine inlet cooling, wet cooling towers, and hybrid cooling towers with a crosswind effect. Some effort is provided to describe the advantages related to direct evaporative cooling when it is applied in thermal power plants and illustrate the research gaps, which have not been filled yet. In particular, typical case studies are intentionally used to compare the cooling performances when direct evaporative cooling… More >

    Abstract Pre-cooling the inlet air of a dry cooling tower by means of a spray can improve the tower performance during periods of high temperature. To study the spray effect on the thermal performance of natural draft dry cooling towers (NDDCTs), in this study 3-D numerical simulations of such a process have been conducted using Fluent 16.2 (a two-way coupled Eulerian-Lagrangian approach). The considered NDDCT is 120 m high and only half system is simulated due to its structural symmetry. Three different spray strategies have been investigated at a typical crosswind speed of 4 m/s, which is the… More >

    Abstract In recent years, water collecting systems, with the associated advantages of energy saving and noise reduction, have become the foundation for the development of a scheme to optimize the structure of cooling towers. To explore the feasibility of this approach for mechanical draft cooling towers, a small-scale experimental device has been built to study the resistance and splash performances of three U-type water collecting devices (WCDs) for different water flow rates and wind speeds. The experimental results show that within the considered ranges of wind speed and water flow rate, the pressure drop of the More >
