what solver for 90° turbulent bender airflow
i want to validate a airflow throw a 90° bender with high Re around 100000-200000, diameter 0,2m
eventually i have to define a rough wall afterwards but first i want to handle the problem in smooth mode...
is there any suggestion on wich solver i have to choose and if there is a solver how high/low y+ should be in this case?
thx for help
Which Y+ value you should maintain doesn't depend on the solver but on the turbulence model.
Low-re model = Y+ < 1
High-re model = 30 < Y+ < ~150
Two layer model = theoretically "arbitrary Y+ < 150", but avoid the range from lets say 2 to 20.
For other solver settings and a recommendation just have a look on the answer to your other post with the same topic from about 2 hours earlier.
By the way, there will be no faster answer when posting twice. Most people here will not earn money with posting hints and hence are not waiting the whole day for new posts. So it can take some time until a question is read by somebody who knows an answer.
