In order to investigate explosive properties of ethylene-air premixed gas in flameproof enclosure with interconnected structure under pressure piling, a 161.5 mm × 250 cylindrical and 500 connected by partition hole (inner diameter 15 mm) were studied. A mathematical model the fluid dynamics combustion reaction was selected perform numerical simulations this using finite volume method. Numerica...

This work describes the development of a hybrid framework Runge–Kutta (RK), discontinuous Galerkin (DG), level set (LS) and direct ghost fluid (DGFM) methods for simulation near-field early-time underwater explosions (UNDEX) in early-stage ship design. UNDEX problems provide series challenging issues to be solved. The multi-dimensional, multi-phase, compressible inviscid fluid-governing equatio...

We investigate the behaviour of a range of economic time series using a Bayesian Markov Switching model that allows for explosive regimes and alternative levels of error variance with potentially t-distributed errors. Our results, generated by Bayesian Model Averaging, find explosive root regimes only in a minority of data series that have previously been found to contain bubbles, once regime s...
