A 3D transient simulation model of the tool heating and cutting fluid cooling of a drilling operation has been developed. The possibility of capturing the physics involved in the heat transfer process in drilling in a simulation model is discussed. Validation of the simulation has been done using thermocouples measuring the temperature of the outgoing cutting fluid. A temperature profile of the cutting fluid was investigated with thermocouples mounted in different positions along the periphery of the drilled hole. Pressure distribution was investigated experimentally to give boundary conditions and furthermore provide information for validating the model.
