Abstract
The paper presents a mathematical modeling approach for a novel drilling
strategy with coolant flow. Numerical tools for efficient simulations of such drilling
applications are explained. We model the fluid flow with the Navier-Stokes equation in a
rotational frame of reference and the solid domain is treated with the Fictitious Boundary
Method (FBM). This enables us to utilize a unified mesh for the solid and fluid part of the
domain and heat transfer between these is treated in an implicit way.
