| Abstract: | Naturalconvective phenomena in pipe with cooled upper wall and tilted, heated lower wall are numerically simulated.The coupling momentum and energy equations are solved by using finitevolume discretizing method and pressure-velocity iteration algorithm.The mechanism of interaction between natural and forced convective is discussed.The numerical method is utilized to analyse the growth uniform of film in metallorganic chemical deposition. |
