The Drift Tube Linac (DTL) of the European Spallation Source (ESS) is designed to operate at 352.2 MHz with a duty cycle of 4 % (3 ms pulse length, 14 Hz repetition period) and will accelerate a proton beam of 62.5 mA pulse peak current from 3.62 to 90 MeV. In this paper the main issues regarding the thermo-mechanical 3D details of the DTL are addressed and a Computational Fluid Dynamics (CFD) model is proposed and validated against the experimental data. The results of these simulations are
