Titreşim yapan borularda ısı transferinin deneysel olarak incelenmesi

Bu çalışmada, belirli genlik ve frekans değerlerinde salınım yapan silindirik borularda ısı transferi ve basınç kayıp karakteristikleri incelenmiştir. Bu amaç doğrultusunda bir titreşim mekanizması dizayn edilmiştir. Salınım frekans değeri f=0.008 Hz ile 1.988 Hz arasında, boyutsuz genlik X=3, 6, 9 arasında ve salınım Reynolds sayısı ise 5000–25000 arasında seçilmiştir. Genliğin ve frekansın ısı transferi ve basınç kayıp katsayısı üzerinde etkili olduğu belirlenmiştir.

Experimental investigation of heat transfer in oscillating pipes

In this study, characteristics of heat transfer and pressure loss of oscillating pipes at certain amplitudes and frequencies were investigated. For this aim, an oscillating mechanism was designed. Experiments were conducted for the oscillating frequency f , in the range of 0.008- 1.988 Hz and dimensionless amplitude X=3, 6, 9. Reynolds number was changed from 5000 to 25000. It was determined that oscillating amplitude and frequency was reasonably effective on heat transfer and friction factor.
