...Mamun Molla; Suvash C. Saha; M.A.I. Khan Purpose The purpose of this paper is to discuss, with numerical simulations, magnetohydrodynamic (MHD) natural convection laminar flow from an isothermal horizontal circular cylinder immersed in a fluid with viscosity proportional to a linear function...

... effects. The fluid viscosity and thermal conductivity are assumed to vary as a function of temperature. Design/methodology/approach The boundary layer equations are transformed to non‐linear ordinary differential equations using scaling group of transformations and these equations are solved...

... into account the finiteness of gas supply availability as well as the effects of surrounding bubbles. The models are based on the application of the conservation of continuity and momentum principles and on constitutive equations to represent the viscosity of the melt. The models are numerically implemented...

... Publishing Limited 2006 Finite element analysis Viscosity Finite difference methods Simulation The finite element method (FEM) is gaining more and more importance in the computational fluid dynamics (CFD), due to its strong mathematical foundation and the capability to deal with complex...

...Mamun Molla; Anwar Hossain Purpose To investigate the effects of chemical reaction on natural convection heat and mass transfer from a sphere with temperature dependent viscosity. Design/methodology/approach The governing boundary layer equations are transformed into a non‐dimensional form...
