Equivalent ratio (ER) is an important factor affecting detonation characteristics and propulsion performance of rotating rocket engine (RDRE). In this paper, the effects different equivalent ratios thrust methane-oxygen RDRE were studied by 2D numerical simulation. The premixed reactants injected through injection holes to simulate discrete on panel in actual RDRE, number was 60 120. results show that there hybrid mode (HDM), co-direction multi-wave (CMM) unstable (UDM) combustion due...
An asphalt mixture has different tensile properties as compared with compressive ones due to the combined effect of aggregate interlock, binder stiffness, and aggregate-binder interactions. This study aims investigate dynamic moduli through indirect four-point bending modulus tests. Firstly, methods for determining mixtures in preceding two tests are developed based on bimodular theory. Then, one determined using methods. It was found that exceed over entire frequency domain both types test....
The Yarkovsky effect on real asteroids is complicated to calculate either by analytical or numerical methods, since they are usually irregular in shape. We propose an index properly characterise the shape of any asteroid, through which can be easily calculated without heavy computations surface temperatures. By analysing energy absorbed and then emitted a element, we find that effective working power produced radiation recoil force this element its contribution both proportional double...
This research explored the effect of aging and blending duration on degree (DoB) performance recycled HMAs, as well actual contribution DoBs to HMA. Nine groups were designed, including one group designed "full group"; "no seven experimental "partial groups" under different combinations RAP materials durations. The volumetric indicators, DoB, moisture susceptibility, high- low-temperature each assessed. It was found that prolonging can effectively restore HMAs containing with serious aging....
Abstract Under the current scouring, submarine cables are prone to be exposed, suspended, and even vortex‐induced vibration (VIV), threatening their mechanical electrical properties. In this contribution, a finite element simulation model of 110‐kV single‐core optical fibre composite cable is established. The natural frequency resonant obtained through wet mode analysis harmonic response analysis. Then VIV simulated by fluid–structure coupling method. Moreover, stress extraction method...
This research comprehensively explored the function of preheating temperature and quantified contribution degree blending (DoB) to performance recycled hot-mix asphalt (HMAs). Five groups were designed, including no group, full three experimental at temperatures 60, 110, 160 °C. It can be found that played a positive impact on DoB HMAs. As increased by 50 °C, about 0.13%–0.2% reclaimed binder additionally activated, tensile strength ratio, shear strength, fracture energy HMAs improve around...
In order to study the influence of impeller eccentricity on performance centrifugal pump, k–ε turbulence model was selected, and ANSYS CFX provided for numerical simulation calculation pump with offsets 0, 1, 3, 5 mm. The results show that increasing, head efficiency become lower. Under condition rated flow, area low pressure at suction surface short blade inlet smaller gradually; however, long larger, tongue larger too. corresponding critical net positive increases in turn, as means...
The Superpave mix design is a process of repeatedly optimizing the aggregate gradation and asphalt content in accordance with specified limits. As one important parameters, number gyrations (Ndes) adopted empirically to be fixed under specific traffic level. Based on concept performance-oriented approach, this study regarded Ndes as variable parameter evaluated influences two cases performance mixture: variables (gradation unchanged) (asphalt unchanged). Two groups experiments were designed....
