<p>Numerical simulations of stoicheiometric H2/O2 detonation in 90-degrees bent pipe were performed with a detailed chemical reaction model at initial pressure P0=0.1 MPa. The scales of pipe were changed two and three times similarly to understand the scale effects on propagation of detonation through the bent section. The results show that the scale effects are small except 2nd peak along the extrados under the present conditions as well as the shock wave propagating in the air-filled bent pipe reported by Edwards et al. As the detonation propagates through the bent section, the Mach reflection near the extrados appears twice and the transverse detonation is formed to collide on the intrados with maximum pressure of 6-8 PCJ. The cell effects on the total impulse are small though the propagation mechanism changes through the bent section. The detonations through the bent section are re-initiated without quenching and they are independent of the cell effects.</p>
