(OP)
Hi all,
I'd be grateful if any body can recommend me any text (text book or so ever) for solving circular plates via FINITE DIFFERENCE METHOD ? specially if it would be supported with illustrative numerical examples...

there seemed to be lots of relevant hits.
another day in paradise, or is paradise one day closer ?

Not really. FEA has no advantage over the FDM or FVM with curved geometry (unless FEA codes now have elements with curved edges. If that's the case then curved elements must be a VERY recent development).
CFD using FDM/FVM are better-suited for any problems with moving fluids, especially heat transfer problems with convection. FEA forces the user to make WAGs on convection coefficients which the user must apply surface-by-surface. WAG boundary conditions lead to WAG results! Junk In = Junk Out. CFD using FDM or FVM does not need convection boundary conditions since it solves the equations of fluid motion and heat transfer together.
I know of just one CFD code that uses FEA and that is CFDesign. I wasted weeks on that code trying to get solutions on meshes so unwieldy that the solution times were on the order of hours. I found it to be extremely difficult to keep mesh densities manageable and frankly couldn't get much done with it, even with CFDesign Tech Support.
