Free-surface flow occurs when a liquid interacts with another fluid, typically air, creating a moving interface between the two phases. Such flows are commonly encountered in tanks, reservoirs, spillways, open channels, marine systems, filling processes, and industrial fluid-handling equipment. Free-Surface Flow Simulation enables engineers to evaluate liquid-surface behaviour before physical testing, helping improve system performance, safety, and operational reliability.
At Experiqs, we perform Free-Surface Flow Simulations to analyze liquid-air interfaces, wave formation, sloshing behaviour, filling and draining processes, surface deformation, and fluid motion under realistic operating conditions. Our simulations help organizations optimize designs, improve operational efficiency, and validate fluid-system performance before implementation.
The presence of a moving liquid surface introduces complex flow behaviour that can significantly affect system performance and stability. Surface waves, splashing, fluid oscillations, air entrainment, and liquid-level variations can influence structural loads, process efficiency, and operational safety.
Free-Surface Flow Simulation enables engineers to visualize and quantify these phenomena under realistic operating conditions. By understanding how the liquid surface evolves during operation, engineering teams can optimize designs, reduce risk, and improve system reliability while minimizing costly experimental testing.
Our free-surface flow simulation capabilities support the evaluation and optimization of liquid-interface behaviour across a wide range of engineering applications.
Free-Surface Flow Simulations are widely applied across water treatment facilities, storage tanks, reservoirs, open-channel systems, marine equipment, hydraulic structures, process industries, energy infrastructure, spillways, and industrial fluid-handling systems where liquid-surface behaviour directly influences performance and safety.
