Single-component adsorption isotherms for CO2, CH4, C3H8, and H2O on SAPO-34, SSZ-13, zeolite T were measured, isosteric heats of estimated. Long equilibration times required C3H8 in SAPO-34 SSZ-13 because diffuses slowly these zeolites, but obtained quickly T. Thus, when CO2 coadsorption loadings measured by temperature-programmed desorption higher than at short times, whereas long as displaced adsorbed CO2. In contrast, CO2/C3H8 mixtures equilibrated the fast diffusion. These measurements...
Ducted fans have been widely used in unmanned aerial vehicles (UAVs) for various operations due to the high efficiency, low noise and safety. Proximity effects caused by confined environment, including ceiling effect (CE), bring significant interference aerodynamic performance of ducted fans, which serves as a main challenge stability. In this study, computational fluid dynamic simulation with sliding mesh technique Unsteady Reynolds Averaged Navier-Stokes (URANS) method is conducted...

The unsteady characteristics ducted flying near ground significant, which may bring stability problems. In this paper, sliding mesh technology is applied Unsteady Reynolds Averaged Navier-Stokes (URANS) method adopted evaluate influence on aerodynamic performance fans. time-averaged results show that leads decrease duct thrust, increase rotor thrust total...
Catalytic oxidation is used to control carbon monoxide (CO) emissions from industrial exhaust. In this study, a mesoporous silica material, KCC-1, was synthesized and as carrier with high specific surface area confine active component FeOx nanoparticles (NPs), the CO catalytic performance of x%Fe@KCC-1 catalysts (x represents mass loading Fe) studied. The experimental results showed that due its large abundant mesopores, NPs were highly dispersed on KCC-1 carrier. particle size very small,...

Abstract Ducted-fan drones are expected to become the main drone configuration in future due their high efficiency and minimal noise. When operate confined spaces, significant proximity effects may interfere with aerodynamic performance pose challenges flight safety. This study utilizes computational fluid dynamics simulation Unsteady Reynolds-averaged Navier–Stokes (URANS) method estimate effects. Through experimental validation, our results show that influence range of lies within four...
Ducted fans are widely employed in unmanned aerial vehicles (UAVs) for civil and military uses because they offer low noise high efficiency. However, dynamic motions close proximity can disrupt the flow patterns aerodynamic behaviors of ducted fans, posing a significant stability risk. In this research, numerical simulations were performed using unsteady Reynolds-averaged Navier–Stokes method mesh technique to assess performance when rising descending effects. The findings reveal that, on...
This paper focuses on the robust adaptive control of a coaxial-ducted-fan aircraft under context significant system uncertainty. To ensure accurate tracking even in presence model uncertainties and disturbances for ducted-fan flight platform, reference architecture is proposed this basis augmentation. With nominal closed-loop as system, overlays inputs top linear time-invariant to compensate real time. allows be tracked rapidly accurately by output uncertain which ensures that performance...
