Research ArticleOpen accessPhrase in the titleBoundary Effect on Marangoni Convection in a Variable Viscosity Fluid LayerN.Z. Abidin, N.M. Arifin, M.S.M. NooraniThe onset of Marangoni convection in a horizontal fluid layer with a free surface overlying a solid layer heated from below is studied. Problem is focused on the effect of the solid layer depth or its conductivity. The viscosity group, Rv, Biot number, Bi, depth ratio, dr and conductivity ratio, kr, are significant on determining the critical Marangoni number Mc … …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 6,915 accessesView PDFCite
