Fuel Injectors and Spray CFD Simulation
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
CFD software such as MSC Cradle, AVL Fire, Siemens Star-ccm+, Ansys Fluent and Converge is well equipped to simulate fuel injectors and spray processes including liquid atomization, drop breakup, collision and coalescence, turbulent dispersion, spray cavitation, drop-wall interaction, and drop evaporation.
Wide array of fuel injection simulation methodology, and robust and well-validated physical models allow us for accurate and computationally efficient simulation of these complex physical processes. In applications such as internal combustion engines, the fuel spray initiates, propagates, and dissipates very quickly on a very small spatial scale.
The combustion process can be strongly affected by the exact nature of the fuel spray: droplet velocity, size, distribution, and physical attributes and for dynamically capture the important physics of the injection process, we need a high-density grid around the spray.
Enteknograte engineering team use advanced CFD tools for simulation and analysis of the injection of liquid fuel via physical models for blob injection, injection distribution, variable rate-shape, discharge coefficient, and hollow cone and solid cone sprays and simulating the mixing and evaporation of multi-component fuel sprays.
Spray and Turbulence
Accurate spray and turbulence modeling is critical for predictive diesel and gasoline combustion simulations. In order to obtain results that are as realistic as possible, we use a wide variety of spray and turbulence modeling such as Reynolds-Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES) turbulence models.
For spray, simulate injection, breakup, vaporization, and other spray-related processes with detail are available. We can perform simulations that are dual fuel or multi-fuel and diesel and gasoline are not the only fuels that we can simulate.
Becasue of deep concern to engine manufacturers are the constantly evolving emissions regulations, To help meet these regulations, we simulate soot and NOx via its detailed chemistry. Soot emissions from gas turbine combustors are increasingly becoming a critical design factor as new particulate matter emissions regulations.
