natural convection
 

hi,

how to include natural convection using bossinique model in simple species transport without reaction phenomenon.?

explantion of problem==>

i had simulated simple mass diffusion is of species (A) in water medium is taking place. now i want to apply temp graient in water medium which causes natural convection which increases mass transfer process. i want study effect of temp gradient on diffussion.

question: how to model this natural convecion in species transport without reaction(diffussion)in fluent.? is it possible using bossuniquemodel ? if so explain?

hi,I realize natural convection in an electrical radiator heated by a resistance

And i would like to know witch solver i should use? if i had to use simple C or not? what must be the relazation coefficients?

thanks Alex

Hi,
did you solve this problem?
i am working on it but i didnt solve..
if you did it..
please help me urgently
