TITLE : TRANSIENT SIMULATION OF IN-CYLINDER AERODYNAMICS AND
TURBULENT FUEL MIXING USING A BODY-FITTED MOVING GRID
BY : CHAM Consultancy Team - F G Mendonca
FOR : E.C. BRITE Project, FACSIMILE
DATE : End 1992
PHOENICS Version : 1.6.6
MODELLING DETAILS :
- Three-Dimensional, Turbulent, Transient flow
- Body-Fitted Moving Grid
- Collaborative project has resulted in the production of an efficient,
geometrically representative and experimentally validated Computational
Design Tool for modelling in-cylinder flow during the non-combustion
part of the engine cycle.
- The use of PHOENICS built-in physical models mean that sufficiently
detailed transient modelling is achieved within a realistic framework
of computational turnaround time.
The pictures (courtesy of GEC ALSTHOM Ruston Diesels Ltd.) are as follows:
- Three-Dimensional grid depicting the curved piston, cylinder head with
inlet and exhaust valve holes, and pre-combustion chamber.
- Velocity vectors along the cylinder head, symmetry plane and piston
- Contours of fuel mass fraction during induction
