چکیده

This study has focused on natural convection in an inclined l-shapedcavity lled with copper-water nanouid. the governing equations including continuity,momentum and energy equations have been discretized with a control volume method(fvm) using the simpler algorithm. a proper upwinding scheme is employed to obtainstabilized solutions. the e ective parameters are solid volume fraction (0; ' 0:05),inclination angle (0 135), shape factor (0:6 2w=l 1) and rayleigh number(101 ra 105). results have been presented as isotherm lines, stream lines, localnusselt number and average nusselt number. the e ects of rayleigh number, inclinationangle and shape factor, as well as the solid volume fraction, have been investigated onthe ow eld and nusselt number. results show that the solid volume fraction and shapefactor, as well as the inclination angle, have important e ects on the ow eld, especiallyon average nusselt number. the results indicate that a decrease in shape factor and anincrease in solid volume fraction lead to an increase in average nusselt number.
