| Abstract: | The present work is aimed at investigating the scope of the numerical prediction method in solving conjugate type of problems,where conduction plays an important role,simultaneously with convection.The continuity,momentum and energy equations are simultaneously solved in the entire solid fluid domain.Results are presented for Rayleigh number in the range of 10 4 to 10 6.The computation result and predictor test show that this procedure can fully reflect conjugate conduction with natural convection in enclosure.A Practical and effective approach has been found for numerical study of conjugate natural convection in square enclosure. |

| Keywords: | square enclosure conjugate heat transfer natural convection numerical prediction Rayleigh number |
