Hydraulics and Fuel Injection Simulation
GT-SUITE’s advanced Navier-Stokes flow solver makes it the ideal choice for hydraulic modeling.
Hydraulics & Fuel InjectionACCURATE MODELING
The extensive library of validated, application-specific components enables efficient building of accurate models with a wide range of complexity; from system level models with imposed component characteristics to more detailed component level models that may include effects such as fluid-structure interaction and leakage. Also included are optional models for cavitation, aeration, and gas transport.
Within the engine domain, it is widely used by OEM’s and suppliers for fuel injection (gasoline, diesel, and alternative fuels), hydraulic VVA, cam phasing, and compression release engine braking. Typical predictions of interest include pressure pulsation, flow rates, valve dynamics, fluid and structure temperatures, leakage, contact stresses, etc. As with all GT-SUITE applications, hydraulic models are easily integrated with other sub-systems to capture interactions and optimize overall system behavior.
