 چالش ها 

Engine Performance and Emissions

• Which combustion concepts can I analyze?
• How can I minimize engine-out emissions and tailor my aftertreatment system?
• Can I optimize the intake and EGR Systems to meet performance, fuel consumption and emission targets?
• Can I accurately predict flow, cavitation and erosion in low and high-pressure injection equipment?
• Is it possible to link nozzle flow and fuel injection modelling?

E-Mobility Concepts

• Is it possible to analyze the thermal behavior of E-drivetrain components?
• How detailed can I investigate the electro-chemistry and electro-magnetics relevant for batteries and fuel cells such as SOFC, PEMFC, TEG, Li-ion and Li-Air batteries?

Thermal Load

• Can I optimize residual stresses in structural parts resulting from heat treatment processes (e.g. cylinder head quenching) or from thermal load induced by heat release (e.g. combustion)?
• Am I able to calculate the flow, pressure drop and heat transfer in components of the cooling circuit considering effects of nucleate boiling?
• Can I use the results to predict solid temperatures, thermal stresses and deformation due to thermal load?

راهکار AVL 

The automatic pre-processor is able to efficiently generate grids for geometries with variable volume and/or featuring moving parts such as, pistons, valves, shafts, gears, etc. Automation shifts the otherwise significant effort required for generating a simulation model from the user to the computer.
The solver utilizes a pressure based segregated solution algorithm. It incorporates implicit time discretization as well as accurate conservative and bounded differencing schemes. High-end turbulence models allow for the precise description of transient effects within an engine or on a significantly larger scale.
The integrated postprocessor offers visualization and supports detailed analysis of results online during the simulation and offline interactively or based on marcros and scripts. In-build features allow the fast generation of charts, colored plots and animations in different formats to support the interpretation of both steady and transient phenomena.
