Abstract
Bu çalışmada Maxwell akişkanların gerdirilmiş yüzey üzerindeki MHD akişımn hareket denklemleri ele allnml§tlr. Manyetik alan direnci degi§ken olup konuma baglidlr. Lie Grup Analizi kullandarak, mekana bagli degi§en manyetik alan ile ilgili denklemlerin grup sitilflaması yaplımıştır. Gerdirilmiş levhayı kapsayan genel simr şartları emme ve püskürtmeli olarak alınmıştır. Simr şartlarından gelen ymrlamalar simetrileri etkilemektedir. Simr şartlarının özel fonksiyon formları için var olabilen benzerlik çözümleri türetilmiştir. Simetriler kullamlarak sabit manyetik alan direnci durumu için benzerlik dönü§ümleri elde edilmiştir. Emme-püskürtmeli veya emme ve püskürtmenin olmadtgl gerdirilmiş yüzey çözümleri elde edilmiştir. Fiziksel parametrelerin çözümlere etkileri gösterilmişir.
Steady state boundary layer equations of an upper convected Maxwell fluid with magneto-hydrodynamic (MHD) flow are considered. The strength of the magnetic field is assumed to be variable with respect to the location. Using Lie Group theory, group classification of the equations with respect to variable magnetic field is performed. General boundary conditions including stretching sheet, suction or injection are taken. Restrictions imposed by the boundary conditions on the symmetries are discussed. Special functional forms of boundary conditions for which similarity solutions may exist are derived. Using the symmetries, similarity solutions are presented for the case of constant strength magnetic field. Stretching sheet solutions with or without suction/injection are presented. Effects of physical parameters on the solutions are depicted.
