چکیده
|
Natural convection of a nanouid consisted of water and sio2 in a squareenclosure cavity have been studied numerically. the sidewalls are maintained at di erentconstant temperatures and the other walls are thermally insulated. two-phase mixturemodel has been used to investigate the hydrodynamic and thermal behaviors of thenanouid for various inclination angles of enclosure ranging from = ??60 to = 60,for rayleigh numbers varying from 103 to 07 and for volume fraction = 0 ?? 6%. thegoverning equations in a two-dimensional space are solved numerically using the nitevolumeapproach. the results show that the average nusselt number increases withgrowth of both rayleigh number and the volume fraction of the nanoparticles. moreover,inclination angle can be a control parameter for nanouid lled enclosure, and the angle, inwhich the maximum average nusselt number occurs for various values of rayleigh numbersand volume fraction, is obtained
