Effects of Magnetic Field, Buoyancy and Conjugate Heat Transfer on Flow over a Vertical Thin Plate

Year 2013, Volume: 16 Issue: 1, 1 - 7, 17.08.2013

Abstract

In this study, effects of magnetic field, conjugate heat transfer and buoyancy have been numerically investigated on flow over a thin vertical plate. The fluid is assumed to be incompressible and dense. The nonlinear coupled parabolic partial differential equations governing the flow are transformed into the boundary layer equations, which are then solved numerically using the Keller box method. The effects of the conjugate heat transfer parameter p, the mixed convection parameter Ri, the magnetic parameter Mn and the electric field parameter E1 on the velocity and temperature profiles as well as on the local skin friction and local heat transfer are presented and analyzed. The validity of the methodology and analysis is checked by comparing the results obtained for some specific cases with those available in the literature.

Abstract

Bu çalışmada, dikey ince bir levha üzerinden akışa manyetik alan, birleşik ısı transferi ve kaldırma kuvveti etkileri numerik olarak araştırılmıştır. Akışkanın sıkıştırılamaz ve yoğun olduğu varsayılmıştır. Akışı karakterize eden, lineer olmayan bağımlı parabolik kısmi diferansiyel denklemler sınır tabaka denklemlerine dönüştürülmüş, sonrasında ise Keller-box metodu kullanılarak numerik çözülmüştür. Birleşik ısı transferi parametresi p, kaldırma kuvveti etkisi Ri, manyetik alan etkisi Mn ve elektrik alan etkisinin E1 sınır tabaka içindeki hız ve sıcaklık ile local sürtünme ve local ısı transferi parametrelerine etkisi gösterilmiştir. Kullanılan yöntemin doğruluğu literatürde bazı özel durumlar için elde edilen sonuçlarla karşılaştırılmıştır.
