CFD Simulation of Reacting Flows and Combustion: Engine & Gas Turbine

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Knowledge of the underlying combustion chemistry and physics enables designers of gas turbines, boilers and internal combustion engines to increase energy efficiency and fuel flexibility, while reducing emissions. Combustion System couples multiphysics simulations incorporating accurate physical models with an advanced chemistry solver to provide a complete end-to-end combustion chemistry simulation capability to optimize products that involve reacting flow.

internal combustion (IC) engines

Simulating internal combustion (IC) engines is challenging due to the complexity of the geometry, spatially and temporally varying conditions, and complex combustion chemistry in the engine. In a complex IC engine case, mesh resolution requirements to capture relevant flow features can vary significantly in time and space. This is a challenge that Adaptive Mesh Refinement can easily solve.


Using Simulation to Optimize Reacting Flows and Combustion

From automobile engines to gas turbine generators, reacting flow and combustion is often the key to energy efficiency, emissions, lifespan, product yield, and other performance parameters. Simulation help look deeper into reacting flow and combustion issues to understand the complex chemical reactions, fluid flow, heat transfer, electrical performance, and other factors that determine the performance of your product. Simulation enables our engineers to evaluate more design alternatives more thoroughly than traditional prototype-based design and development methods.

Our Engineers can confidently diagnose design alternatives to understand which potential design changes have the best change of improving product performance and evaluate enough design alternatives to get the design right before building a physical prototype. In such complicated Multiphysics environment including different solid and fluid and interaction between fields, enforce us to use advanced computational tools with innovative methods to capture real-world simulation and optimize system to reduce cost and maximize performance considering short time for design in world competition.

Conjugate Heat Transfer for Predictive Fluid-Solid Heat Transfer

We simulate fluid flow and assume that the walls of the container were at a constant temperature or even adiabatic. In reality, however, there may be significant heat transfer between the fluid and its container, and thus our CFD simulation must be include this phenomenon. The internal combustion engine is one example of such an application. The internal combustion engine industry is moving toward simulating the entire system rather than independent components.

Conjugate heat transfer (CHT)—the simultaneous prediction of heat transfer in both the fluid and solid portions of the domain—is of critical importance in a full-engine simulation. The accuracy of the predicted combustion in the cylinder is dependent on the temperature boundary conditions in the cylinder. By considering heat transfer in the metal components (e.g., the cylinder head, liner, piston, etc.) in the simulation, the cylinder wall no longer has a user-specified temperature, but instead has temperatures predicted as part of the system simulation.
