governing equation of sliding mesh
 
for transient simulation of rorating machine, I used sliding interface(sliding mesh) technique applied for it.

however, I confuse about the governing equations. For the rotating domain, it used navier-stoke equation that include corioris and centifugal force(rotating frame of reference fomulation), or used normal navier-stoke equation.

thank you for answer,

Re: governing equation of sliding mesh
 
Hi I study about simulation of "centifugal Casting". I have your problem too. i see some paper that use normal N.S Equation but add Centrifugal term to it. but when fluid reach to rotational surface we want too use rotational boundary condition. i try to find a good solve for it if you have any idea pleas inform me.I inform you about my result too.
