diffusion Term for add. Variable
Hello,
How can i get ride of the diffusion terms in the transport equation for additional variable. I am trying to transport number density like entity but in the theory there are only Source terms on the right hand side of the equation. Thx Jessica |
I do not understand what you mean.
Do you want to have a transport equation with no diffusion? Just select the transport equation option for the additional variable in this case. |
i am using this transport equation but there exist the diffusion term.
In fact i want to implement an equation like this for the Droplet number Density (dN/dt)+(dUi.N)/(dxi)=Source that means without effect of the turbulent diffusion.. |
So can't you just use a convection only additional variable?
|
Yes Convective time dependent variable but how?
|
Add an additional variable, and set it to a transport/convection equation.
|
that is what that i did but there exist these diffusion terms in the equation of.
|
What diffusion terms? There are not diffusion terms in the convection additional variables. And even if there are, why not just set the diffusion coefficients to zero?
|
There are Diffusion Terms in the Transport equation for add. Variabel. And please tell me how to set the Coefficient to zero.
|
including both laminar and turbulent diffusion... in the theory of the transport equation for the number density of droplet, bubbles and other particles, no diffusion terms and included..
