“…The considered models can approximately predict this region. Another parameter affecting cyclone efficiency is the vortex finder length (Figure 7) Experimental data (Hsiao et al [16]; Kim et al [10]; Zhu and Lee [12]) were used to deter mine the prediction efficiency of the models. Looking at the experimental results from these studies, the critical diameter generally increases up to a specific value with increas ing s value, and then decreases.…”

“…Iozia and Leith [9] conducted experimental studies at different inlet velocities in a cyclone with a diameter of 250 mm. Kim et al [10] stated that, for a cyclone separator with a diameter of 76 mm, at different inlet velocities, the best efficiency for the cyclones in their experimental studies was at an inlet velocity of 15 m/s. Moore and McFarland [11] conducted experimental studies on cyclone separators with four different diameters, while Zhu and Lee [12] considered cyclone separators with different geometries and a diameter of 30.5 mm at different inlet velocities.…”

“…The cyclone vortex finder length is one of the most-studied geometric parameters. In their experimental study, Kim et al [10] measured the critical diameter values with vortex finder length of 28, 49, and 75 mm under different inlet velocities. They concluded that an increase in the length first decreases the critical diameter and then increases it.…”

Cyclone separators are used in multi-phase flows for phase separation or classification. Pressure drop and separation efficiency are essential parameters for determining the performance of a cyclone separator, and critical diameter is an important parameter related to cyclone separation efficiency. In this study, we investigate the critical diameter prediction ability of various mathematical models; in particular, approximately 400 experimental data available in the literature, reflecting different geometries and operating parameters, are used to investigate the critical diameter prediction ability of the selected models. These data are calculated using ten mathematical models selected among the most widely used models which operate based on different principles, and the associated critical diameter values are determined. These calculated values are then compared with those obtained in the experimental studies. As a result, there are many parameters affecting the performance of cyclone separators. The fact that some of these parameters are not used in the models can lower the prediction accuracy of the model, depending on the context. For this reason, the parameters for which the models give better results are analyzed in detail. According to these results, users can choose a model more appropriately. In addition, an absolute evaluation is provided, demonstrating that the models provide important ideas regarding cyclone performance.

“…[73], and the agglomeration of fine particles was observed at the initial stages. Ahuja et al [74] and Kim et al [75] reported that the collection efficiency of fine particles increases substantially with humidity. However, few studies have investigated the effects of dust particle properties, such as particle humidity, particle temperature, and classification, through experimental and numerical simulations.…”

Cyclone separators are used extensively in diverse applications and research domains to collect particle-laden flows. Despite the technological advances in this field, no bibliometric reports on this topic have been documented. Understanding the state of the art in this field is crucial for future research. Using bibliometric mapping techniques, this study examined the quality, quantity, and development of research on cyclone separators. Relevant data were extracted in plain text formats through search queries refined by publication year (2000–2021) and document type (article and review articles). A sample of 487 publications, limited to the Web of Science Core Collection (WoSCC) database was used for the bibliometric analysis. Data analysis was performed using RStudio software package (R Bibliometrix tool). Of the 487 publications that appeared during this period, China had the highest number, followed by the Islamic Republic of Iran, whereas chemical engineering journals dominated the cyclone separator research publications. Collaboration among the researchers was low (MCPR < 0.5000). Furthermore, the pattern of single-author publications was found to outstrip that of the multiple-author publications. The findings suggest that researchers in various parts of the world, particularly Africa and the Middle East, should route their research efforts towards this field, in light of the lack of publications from these regions on this subject. The aim of this study was to serve as a seminal reference for potential technological research directions and collaboration among researchers in this and other related fields.

Bir siklon ayırıcıda düşük basınç düşüşü ve yüksek partikül tutma verimi gerçekleşmesi istenir. Bu bakımdan siklon ayırıcıların performanslarının tayininde kritik çap önemli bir parametredir. Performansa etkiyen önemli parametrelerden biri de hızdır. Bu çalışmada giriş hızı değişiminin etkisini tahmin için kullanılan ve literatürde mevcut matematik modellerden 10 tanesi yine literatürde mevcut hız değişimini inceleyen yaklaşık 120 farklı deneysel veri esas alınarak incelenmiştir. Hız değişimi etkisinde matematiksel model hesaplamaları ile elde edilen kritik çap değerleri ve değişim oranları ile deneysel çalışmalarda verilen kritik çap değerleri ve değişim oranları kıyaslanmıştır. Sonuçta kritik çapın hızın karekökünden daha hızlı değişim gösterdiği görülmüştür. Buna göre kritik çap tahmininde hızın etkisi açısından hıza bağlı ilave terimler içeren veya sürtünme kayıplarındaki değişimi dikkate alan modellerin daha duyarlı olduğu sonucuna varılmıştır.
