Abstract

In addition to scientific papers discussing the known destructive characteristics of Vortex-Induced Vibrations (VIV), the number of studies demonstrating different ways to harness the phenomenon has increased in recent years. Various research endeavors leveraging the physics of VIV, such as electricity generation, mechanical energy production, and the development of residential water meters, highlight the significance of this subject. In alignment with these studies, this paper first provides a physical explanation of VIV on circular cylinders. Subsequently, it discusses a recently patented device designed to harness VIV for water pumping, along with presenting a mathematical model applicable to its calculations. Furthermore, the characteristics of three different rivers from different geographical regions of Turkey - Kızılırmak, Büyük Menderes, and Meriç Rivers - are analyzed at specific coordinates. Preliminary calculations are conducted for three distinct setups of VIV-driven water pumps tailored for each of these rivers, evaluating their pumping capacity, maximum pumping heights, and corresponding flow rates. Thus, unveiling the potential contribution to agricultural irrigation and afforestation efforts.

Girdap Kaynaklı Titreşimlerle Tahrik Olan Su Pompası: Türkiye Akarsularında Potansiyel ve Performans Değerlendirmesi

Abstract

Girdap Kaynaklı Titreşimler (GKT) konusunun bilinen yıkıcı – tahrip edici özelliklerinin tartışıldığı bilimsel yayınlara ek olarak, son yıllarda ortaya konan ve fenomenden farklı şekillerde yararlanılabildiğini gösteren çalışmaların sayısı artmaktadır. Olayın fiziğinden yararlanarak elektrik üretimi, mekanik enerji üretimi ve mesken tipi su sayacı geliştirilmesi gibi farklı çalışmalar konunun önemini artırmaktadır. Çalışmada öncelikle dairesel silindirler etrafında meydana gelen GKT olayının fiziksel izahatı yapılmıştır. Daha sonra GKT ile tahrik edilerek kendi kendine su pompalaması planlanan ve son yıllarda patentlenmiş bir düzenek fikri tartışılmıştır. Bu su pompasının hesaplamalarında kullanılabilecek matematiksel bir model sunulmuştur. Ardından Türkiye’nin üç farklı coğrafi bölgesinde yer alan Kızılırmak, Büyük Menderes ve Meriç Nehirleri için belirli koordinatlardaki akarsu karakteristikleri çıkarılmıştır. Özellikleri belirlenen akarsuların her birinde kullanılması planlanan GKT tahrikli su pompaları için üç farklı düzeneğin ön hesabı yapılmıştır. Ön hesaplamalar ile temel özellikleri belirlenen düzeneklerin bu üç akarsuda pompalayabileceği su miktarı depolanacak yükseklikler ve karşılık gelen debiler cinsinden ortaya konmuştur. Böylece tarımsal sulama ve ormanlaştırma çalışmalarına ne kadar katkı sağlayacağına dair potansiyel ortaya çıkarılmıştır.
