Abstract: In a previous work, we explored liquid xenon (LXe)-based positron targets as an alternative to conventional high-Z metallic targets for high energy physics applications. In this paper, we apply computational fluid dynamics simulations to the LXe target and containment vessel, including entrance and exit windows. We design a flow geometry that is able to quickly move heated LXe from previous beam pulses out of the target volume without significant boil-off. While our simulations indicate that the temperature of the exit window can be kept stable, the peak energy deposition density exceeds the widely accepted damage threshold of 35 Jg$^{-1}$ for ILC-like conditions.
