Open AccessEffect of channel expansion angle near injector outlet on a rotating detonation engine performance
A rotating detonation engine (RDE) is expected to achieve a pressure gain (PG) in which the total pressure of the product at the engine exit exceeds the total pressure of the supplied oxidizer. However, many n...

Open AccessSearch for lepton-flavor-violating τ decays into a lepton and a vector meson using the full Belle data sample
Charged-lepton-flavor-violation is predicted in several new physics scenarios. We update the analysis of τ lepton decays into a light charged lepton (ℓ = e± or μ±) and a vector meson (V0 = ρ0, ϕ, ω, K*0, or ...

Open AccessSearch for lepton-flavor-violating tau-lepton decays to ℓγ at Belle
Charged lepton flavor violation is forbidden in the Standard Model but possible in several new physics scenarios. In many of these models, the radiative decays τ± → ℓ±γ (ℓ = e, μ) are predicted to have a sizeable...

Investigation into the effective injector area of a rotating detonation engine with impact of backflow
For rotating detonation engines, the high-pressure region behind the detonation causes backflow into the plenum, making it difficult to properly design injectors to achieve the target pressure balance due to b...

Investigation of High-Frequency Pulse Detonation Cycle with Fuel Phase Transition
To achieve the pulse detonation (PD) operation at high frequency, it is essential to shorten deflagration-to-detonation transition (DDT). Increasing the initial pressure of detonable mixture is a valid way to ...
