Abstract

The present paper investigate the effects of magnetic field (MHD), Richardson and suction on an exponentially expanded infinite plate by studying the convective heat and mass transfer of a non-Newtonian incompressible viscous and electrically conducting fluid. Cross-diffusion impacts are also taken into consideration. The governing partial differential equations (PDEs) are transformed into ordinary differential equations through the application of well-posed similarity transformation variables (STVs). Thus, the transformed dimensionless equations are solved analytically by integrating factor approach and the resulting solutions are simulated with an efficient stability numerical algorithm known as Mathematica. The results are displayed in tabular and graphical forms while the effects of various parameters on the velocity, temperature, concentration, skin–friction coefficient, Nusselt and Sherwood numbers are discussed in details. It was found that velocity falls when magnetic field and suction parameters increase. Also, the temperature and nanoparticle concentration decreases as suction number rises but are enhanced as diffusion-thermo and thermal-diffusivity parameters rise. An increase in Richardson and Prandtl numbers leads to a decrease in skin-friction and upsurge in the rate of heat transportation. The results of this study can be used to advance the design, operation, and performance of various systems encountered in industrial and scientific applications.

MHD Richardson Akışının Emiş ve Çapraz Difüzyon Etkileri ile Üstel Olarak Gerilmiş Sonsuz Bir Plakadan Geçmesinin Analizi

Abstract

Bu makale, Newtonyen olmayan sıkıştırılamaz viskoz ve elektriksel olarak iletken bir akışkanın konvektif ısı ve kütle transferini inceleyerek, manyetik alanın (MHD), Richardson ve emmenin üstel olarak genişleyen sonsuz bir plaka üzerindeki etkilerini araştırmaktadır. Çapraz difüzyon etkileri de dikkate alınır. Geçerli kısmi diferansiyel denklemler (PDE'ler), iyi konumlanmış benzerlik dönüşüm değişkenlerinin (STV'ler) uygulanması yoluyla sıradan diferansiyel denklemlere dönüştürülür. Böylece, dönüştürülen boyutsuz denklemler, entegre faktör yaklaşımıyla analitik olarak çözülmekte ve elde edilen çözümler, Mathematica olarak bilinen etkin kararlılık sayısal algoritmasıyla simüle edilmektedir. Sonuçlar tablo ve grafik formlarında gösterilirken, çeşitli parametrelerin hız, sıcaklık, konsantrasyon, yüzey sürtünme katsayısı, Nusselt ve Sherwood sayıları üzerindeki etkileri ayrıntılı olarak tartışılmaktadır. Manyetik alan ve emme parametreleri arttıkça hızın düştüğü bulunmuştur. Ayrıca emme sayısı arttıkça sıcaklık ve nanopartikül konsantrasyonu azalır, ancak difüzyon termo ve termal yayılma parametreleri yükseldikçe artar. Richardson ve Prandtl sayılarındaki artış, cilt sürtünmesinin azalmasına ve ısı aktarım hızının artmasına neden olur. Bu çalışmanın sonuçları, endüstriyel ve bilimsel uygulamalarda karşılaşılan çeşitli sistemlerin tasarımını, işletimini ve performansını geliştirmek için kullanılabilir.
