This webinar demonstrates how Flownex is used to model, analyze, and optimize modern data center cooling systems, with a strong focus on hydraulic studies and transient thermal behavior. It shows how cooling system networks can be imported directly from Autodesk Revit, allowing engineers to rapidly evaluate flow distribution, pressure losses, and pump sizing across complex chilled water systems. The presentation then explores thermal ride-through and IT load ramp scenarios, illustrating how Flownex predicts the dynamic response of chillers, buffer tanks, pumps, fan walls, CDUs, and control systems during power interruptions and rapid load changes. By accurately capturing both hydraulic and thermal interactions, engineers can identify design weaknesses, validate control strategies, and ensure compliance with cooling performance requirements before deployment. Through its physics-based models, advanced transient solver, and integration with tools such as Revit and CFD software, Flownex enables faster, more reliable, and more efficient data center cooling system design.
