The beam window, which separates the vaccum beam tube and the spallation target, is one of the most crucial components in a liquid metal target of the accelerator-driven subcritical system (ADS). The major difficulties in the window design are the protection against radiation damage and heat removal. It is a challenge to cool down the beam window sufficiently due to its high heat load.Numerical simulations of the fluid flow are performed by using the PHOENICS code for the proposed spallation target of ADS. The main objectives of the study are to investigate the flow behavior in the target systems, especially around the beam window, and to make contribution to the
