Mole fraction imposed

Mole fraction imposed

Ver: 0 DESCRIPTION Allows the user to specify the mole fraction boundary condition along a boundary set for the mass transfer equation (chemical reactions).

The default value is zero constant.

OPTIONS

-1 Upper level menu

The value of the mole fraction is accepted

1 Constant

The current value of the mole fraction is constant on the corresponding boundary line or face

2 Linear function of coordinates

A linear dependence of the mole fraction upon the current spatial coordinates is selected

NOTES Mole fraction condition is an essential boundary condition for the mass transfer equation. There should be at least one mole fraction condition on the boundary of the domain in order to guarantee uniqueness of the solution. SEE ALSO
