a question about the linearizing of source
 

hi everyone! how to linearize a source if there are more than one variable in it. thanks

you only have to linearise it with respect to the dependant variable. for example if you include a source term in the k equation you linearise it with respect to k. you can treat all other variables as constants. get Numerical Heat Transfer and Fluid Flow by Patankar. There is a very good section in it on source linearisation.
