These technical papers document the CFD methods, validation work, and modeling practices behind CoolSim. Several date from our earlier research — the physics and methodology remain foundational. For the latest applications, including hyperscale thermal design, chiller performance, and liquid cooling, see our recent webinars and field notes.
