Title:

MULTIPORT APPROACH APPLIED TO THERMOFLUID SYSTEMS

Summary :

ABSTRACT. THE PURPOSE OF THIS PAPER IS TO PRESENT HOW A NUMERICAL THERMOFLUID LIBRARY WAS DEVELOPED. THIS LIBRARY COMPRISES A SET OF BASIC COMPONENTS FROM WHICH IT IS EASY TO MODEL LARGE THERMAL-HYDRAULIC NETWORKS AND MODIFY, IF REQUIRED, THE DESIGN OF THE SYSTEM STUDIED. THESE BASIC COMPONENTS WERE SPECIFIED BASED ON BOND GRAPHS AND MULTIPORT METHODS AND DEVELOPED BY USING LUMPED PARAMETER MATHEMATICAL MODELS APPROACH. TO COMPLEMENT THE THERMOFLUID LIBRARY, THE COOLING SYSTEM LIBRARY IS PRESENTED. THIS IS AN EMPIRICAL LIBRARY COMPOSED OF A SET OF SPECIFIC COMPONENTS, WHICH ARE CONSTRUCTED BASED ON EXPERIMENTAL DATA. THIS PAPER ENDS UP WITH AN OVERVIEW OF THE VALIDATIONS THAT HAVE BEEN MADE AND THE EXTENSIONS PLANNED TO OBTAIN BETTER RESULTS FOR ENGINE COOLING SYSTEMS. KEYWORDS: ENGINE COOLING, THERMAL SYSTEM, BOND GRAPHS, MULTIPORT, LUMPED PARAMETERS
