Modelling in-cylinder combustion
Internal Combustion Engine (ICE) powertrains are the backbone of powerful, efficient, and cost-effective propulsion in numerous sectors, spanning automotive, marine, aerospace, construction, power generation, and more. Realising the full potential of ICEs begins with a deep understanding of combustion processes, leading to cleaner combustion, superior propulsion efficiency, emissions reduction, and a more sustainable economy.
At Realis, we are passionate about delivering accurate, flexible, and fast combustion modelling capabilities for our customers. This drive underpins our combustion modelling from the inception with correct property definition and blending of complex fuels through modelling of combustion kinetics and flame propagation and to the analysis of the effect of the combustion on power, thermal and emissions response of your ICE powertrains. Realis Simulation offers a comprehensive modelling capability – from conventional gasoline, diesel, and kerosene blends to next-generation drop-in biodiesels, synthetic hydrocarbons, non-carbon fuels such as hydrogen and ammonia and revolutionary e-fuels, empowering our customers.
Our simulation toolsets can quickly and accurately provide answers to the ‘What ifs’ which are vital to the overall assessment of different fuel types.
WAVE is a 1D Computational Fluid Dynamics (CFD) that solves the Navier-Stokes equations governing the transfer of mass, momentum, and energy for compressible gas flows, and includes sub-models for combustion and emissions.
VECTIS is a 3D CFD tool that uses cutting edge kinetics, flame propagation and emissions models for conventional hydrocarbons, e-fuels and synthetic fuels including hydrogen.
FEARCE-Vulcan uses a unique iterative Finite Element solution that considers all the heat paths in detail to deliver a reliable and accurate predictive tool for conclusive structural investigations.
