The present paper considers gasdynamic behavior due to chemical reactions in reflected-shock flowfields in shock tubes by comparing experiments, numerical simulations and analyses. Pressure measurements have been carried out in the reflected-shock region in H_2-O_2-Ar mixture by using a diaphragmless shock-tube apparatus. Comparisons between simulations and experiments have shown that detailed modeling can successfully simulate reactive gas flows in shock tubes. Results of simulations verify that the analytical linearized relations hold between chemical energy and variations of the physical properties on the shock-tube end-wall for highly lean combustible gas. Some discrepancies between the simulations and the analyses, which appear for moderately lean cases, can be estimated by considering acceleration effects of the reaction front.
