CONVERGE™ is ideally suited for simulating Diesel engines and is used by engine manufacturers such as Caterpillar Inc. Features such as easy inclusion of complex and moving geometries, adaptive mesh refinement, and a suite of state-of-the-art spray and combustion models makes CONVERGE™ the ideal CFD code for all of your IC Engine applications.
With CONVERGE™, full engine simulations can be performed without the need for mapping between different codes. The image below shows the velocity field during the intake stroke for a small bore, high speed direct injection Diesel engine.
Sometimes it is desired to only simulate a portion of the combustion chamber for computational efficiency. The video below illustrates a Diesel engine combustion simulation performed in one-sixth of the combustion chamber. Colors represent the temperature field.
It is critical to have accurate spray models and adequate mesh resolution if engine simulations are to be predictive. The video below illustrates a combusting Diesel spray simulation using adaptive mesh refinement. Colors represent the temperature field.
