Matching of High Output Diesel Engines with Associated Turbomachinery: First Paper: A General Approach to the Computer Solution of Single- and Two-Stage Turbocharged Diesel Engine Matching
The first paper describes the general approach adopted in the solution of steady-state matching of single-stage turbocharged engines with fixed and variable geometry turbines and two-stage turbocharged engines developed from general principles first reported in (1). Individual components are represented either by systems of equations or by multi-dimensional numerical arrays embodied in separate subroutines which are called from a main-linking programme containing the overall matching equations. Appropriate iterative procedures from initially assumed values of boost and turbocharger speed (for single- or two-stage arrangements) are briefly described.
The programmes have been run both in batch processing and interactive mode, and in the latter form have been found particularly valuable as teaching aids.
