A soundscape carries the culture and memories of historical cultural areas, capable evoking people’s emotions towards a place. This paper aims to explore influence on sense place in areas using mixed-method approach. Conducting on-site measurements, questionnaires, semi-structured interviews four Taiyuan, China, this research utilized structural equation modeling grounded theory for analysis. Research findings: Firstly, soundwalk method identified 11 categories soundscapes main sources noise...
The deformation of the Mach stem in pseudo-steady shock wave reflections is investigated numerically and theoretically. numerical simulation provides typical flow patterns reveals differences caused by high-temperature gas effects. results also show that wall jet, which causes deformation, can be regarded as a branch mainstream from first reflected shock. A new theoretical model for predicting developed considering volume conservation. predictions agree well with wide range test conditions....
Side branch Helmholtz resonators (HRs) are widely used to control low frequency tonal noise in air duct system. The passive resonator only works effectively over a narrow range around resonance frequency. Changes the exciting and temperature will decrease reduction performance. Many studies have been conducted on incorporating with active tuning of HRs. objective this study is effect flow semi for control. Owing Mach number flow, discontinuity condition at joint analytically formulated...
Abstract This work studied the rheological properties and magnetorheological (MR) mechanism of dry fluid (MRF) under various working modes. A novel simulation method combining discrete element computational dynamics was developed, in which bilateral coupling between particles flow field matrix (air) considered. The microstructures mechanical redispersion process, shear mode, valve mode were systematically simulated for first time. results indicated that MRF presented superior property...
The influence of high temperature effects on the protrusion Mach stem in strong shock reflection over a wedge was numerically investigated. A two-dimensional inviscid solver applies finite volume method and unstructured quadrilateral grids were employed to simulate flow. Theoretical analysis also conducted understand phenomenon. Both numerical theoretical results indicate wall-jet penetrating forward is responsible for occurrence protrusion. degree seems depend thermal energy buffer capacity...
Large eddy simulations are performed to explore transitional characteristics with parametric variations under initial conditions for rarefaction-driven Rayleigh–Taylor mixing flows and develop a model the prediction of transition onset. Three-dimensional, multi-mode perturbations imposed on diffuse interface excited by rarefaction wave, resulting in large but non-constant acceleration. Initial investigated here profoundly impact characteristic times through variation net contributions...
As a priority of China’s regional development strategy in recent years, promoting the ecological protection and high-quality Yellow River Basin is one important tasks to boost country’s economy also key central region at this stage. High-quality based on perspective culture, sports, tourism integration significant for economic revitalization. In order measure resources basin, study applied CRITIC model Mathematical Statistics, fuzzy comprehensive evaluation model, entropy weight TOPSIS...
The differences in the heritage perspectives of key stakeholders form an indispensable basis for formulating appropriate conservation strategies living heritage. However, existing practices, between experts and local residents, who are both stakeholders, often arise from expert experiences rather than being accurately measured. This study regarded traditional Chinese villages Luzhong region as a case investigation quantified such differences. Initially, this provided comprehensive...
When a shock wave impacts roughened metal/gas interface, metal ejecta particles emit and transport in the gas. The exchanges of momentum energy between gas occur. If active reactive gas, heat released by chemical reaction could change these exchanges. In this paper, we use numerical simulations to study solid cerium transporting vacuum, non-reactive gases. emitted self-similarly expand neglecting particle interaction. (He), slow down resistance have with (D2), also down. exothermic induce...
The photon Doppler velocimetry (PDV) spectrum is investigated in an attempt to reveal the particle parameters of ejecta from shock-loaded samples a vacuum. A GPU-accelerated Monte–Carlo algorithm, which considers multiple-scattering effects light, applied reconstruct light field and simulate corresponding PDV spectrum. influence velocity profile, total area mass, size on simulated spectra discussed qualitatively. To facilitate quantitative discussion, novel theoretical optical model proposed...
Shock-induced micro-jets and micro-spalls on metal surfaces the subsequent mixing with surrounding gas are of interest for a wide range applications, such as inertial-confinement fusion armor design. This study interprets micro-spalled permeation into evolving porous structure created by liquid debris. A technical route is established based combination fluid mechanics in media shock dynamics. The topology studied through molecular dynamic simulation, which captures major characters...
Abstract Expansion chamber mufflers are often used for duct noise control of building ventilation systems. In this paper, the periodic arrangement expansion muffler is proposed to improve sound attenuation performance. The investigated theoretically with Bloch wave theory and a case calculated distance between length same. results reveal that transmission loss enhanced by arrangement.
