Multi-threading in Java enhances computational performance and facilitates the development of parallel software. To obtain high performance on multi-core systems, this study develops a multi-threaded simulation code using Java for the chemical reacting flow of ethanol. Three ethanol reaction models were implemented in this code to investigate the effects of multi-threaded processing on three multi-core CPUs. The computational load for the chemical reaction significantly increases with the number of chemical equations and high temperature portion of the domain. To enhance parallel performance, the domain in which the chemical reaction occurs is appropriately decomposed at each time step, resulting in improved parallel performance.
► We develop the multi-threaded simulation code for chemical reacting flow with Java. ► Three ethanol reaction models are compared in terms of computational cost. ► Load of chemical reaction is balanced properly by dynamic domain decomposition. ► Parallel speedup for the complicated chemical reaction model is better.
