Calibration of Model of Flow and Heat Production Inside a Combustion Engine
Original language description
A short description of the calibrated model of compressible flow, diffusive-advective mass and heat transport, and combustion inside the cylinder of a combustion engine is made and results of its calibration for one measured test are presented.The firstpart of the article is devoted to the structure and a brief description of the model. The problem is modelled by a sequence of three isochoric processes (changes of flow and pressure fields by finite elementmethod, transport of mass and heat by finite volume method, and heat production and mass change by ordináty differential equation model) and adiabatic volume change (represented by change of mesh and recomputation of all fieldsof physical properties due to adiabatic process). In the second part of the article, there is the calibration of modelled global energy production with measured data described and its result shown. Then the conclusion from the results is done.
