Abstract:
The ctTecls of the temperature dependent thermal condllctivity on Magnelohydrodynamic
(MHO) free convection flow along a vertical flat plate with heat conduction und viscous
dissipation have been investigated. The governing eqll1tlLOnS,,;ll1 associulcd boundary
conditions for this phenomenon arc co,,,crlcd tel ciimcilsionb, form u~ing suitable
transformations, the governing equations containing the equation of continuity,
momentum and energy. The transformed uon.lillcar ordinary partial differential equation,
are then solved using 11m implicit [,nile differellce method with Kelier-box scheme.
rORTRAN 90 is used (0 perform cOl1lputalionuljob and the post processing software
TECPLOT has been used to display the numerical results graphically. Thc re;ullS in tenn~
