SABİT SICAKLIK KONFİGÜRASYONUNDA ORTAM SICAKLIĞI VE SOĞUK DUVAR SICAKLIĞININ OSİLASYONLU YÜZEY GERİLİM HAREKETİNE GEÇİŞE ETKİLERİ

Year 2008, Volume: 3 Issue: 2, 191 - 204, 01.12.2008

Abstract

Bu araştırma, Sabit Sıcaklık Konfigürasyonunda, yüksek Prandtl sayısına sahip,
silindirik bir kaptaki akışkanın kararlı ve osilasyonlu yüzey gerilimli akış hareketi
deneysel olarak araştırılmıştır. Deney akışkanı, 30 mm çapındaki deney silindirinin
simetri eksenine yerleştirilen silindirik bakır çubuk tarafından ısıtılmış ve deney
silindirinin dış kenarına sarılan bakır boru içerisinden geçen su ile soğutulmuştur.
Deney akışkanı olarak kinematik viskozitesi 5 cSt olan silikon yağı kullanılarak belli
şartlar altında akış hareketleri ve sıcaklık osilasyonları gözlenmiştir. Akışkanın serbest
yüzeyinden ortama olan ısı kaybının, farklı ortam sıcaklıklarının ve farklı soğuk duvar
sıcaklıklarının kararlı haldeki akışkan hareketinin periyodik osilasyonlu akış hareketine
başlama noktasına etkileri araştırılmıştır.
