| Description
| - Transient engine operations are modeled and simulated with a 1-D code (GT Power) using heat release and emission data computed by a 3-D CFD code (Kiva3). During each iteration step of a transient engine simula-tion, the 1-D code utilizes the 3-D data to interpolate the values for heat release and emissions. The 3-D CFD computations were performed for the compression and combustion stroke of strategically cho-sen engine operating points considering engine speed, torque and excess air. The 3-D inlet conditions were ob-tained from the 1-D code, which utilized 3-D heat release data from the previous 1-D unsteady computations. In most cases, only two different sets of 3-D input data are needed to interpolate the transient phase between two engine operating points. This keeps the computation time at a reasonable level.

- Přechodový režim je modelován kombinací 1-D programu (GT Power) v kombinaci s 3-D programem Kiva, z něhož se používají předpovězené průběhy vývinu tepla a výsledné koncentrace emisí. Výpočet je iterační, 1-D program předpovídá trajektorii stavů motoru a 3-D kód se počítá ve strategicky vybraných bodech trajektorie. Mezi 3-D výsledky, uloženými do databáze hoření, se v 1-D kódu interpoluje. Pro většinu případů stačí 2 iterace, cca 50 provozních bodů časově velmi náročných simulací ve 3-D. To významně urychluje simulaci a otevírá možnosti optimalizace. (cs)
