REACTION HEAT FLUID NUMERIC VALUE SIMULATION DEVICE

PROBLEM TO BE SOLVED: To realize a reaction heat fluid numeric value simulation device capable of evaluating influence effected on the knock occurrence timing and a position by the cycle initial temperature and the concentration distribution. SOLUTION: A flow field of an analytical area is analyzed by reading calculation grating data, initial condition data and boundary condition data (Step P1-P3). A determination is made on whether or not a searching particle is generated (Step P4), and when the particle is generated, position coordinates of the searching particle are calculated, and processing is finished when time is the simulation finishing time (Step P7 and P8). When a determination is made that the particle is not generated in the Step P4, a determination is made on whether or not the particle is generated in a calculation area. When generating the particle, the searching particle is generated in a calculation system (Step P6), and then, the processing of the Step P7 and P8 is performed. A result provided from an analysis is outputted to an external storage medium as image screen output and a file (Step P9), and the analysis is finished (Step P10). COPYRIGHT: (C)2010,JPO&INPIT
