Cover Story: This article provides an in-depth evaluation of a massively parallel Direct Simulation Monte Carlo (DSMC) kernel called SPARTA (Stochastic Parallel Rarefied-Gas Time-Accurate Analyzer). This study focuses on the fundamentals of applying DSMC methods in rarefied hypersonic flows, which are crucial for understanding high-altitude aerospace applications. The evaluation emphasizes the scalability, accuracy, and computational performance of SPARTA, a critical tool for advanced simulations in rarefied gas dynamics. This research lays the groundwork for improving simulation techniques in aerospace engineering and high-speed vehicle design. View this paper
