Investigating the throttling characteristics of Rocket-Based Combined Cycle (RBCC) engines in ejector mode is crucial for adapting to varied flight mission demands. This study employs validated RANS numerical methods investigate effects on an experimental kerosene-fueled RBCC engine under two representative conditions: ground take-off (Mach 0) and supersonic 2.0). Results indicate that, at Mach 0, reduces entrained secondary stream increases mixing efficiency, but exacerbates losses, which...
Flame stabilization characteristics in the supersonic combustor with a circular cross-section strut were experimentally investigated. The Mach number, stagnation pressure, and temperature of inflow 2.52, 1.60 MPa, 1486 K, respectively. Compared to wedge-shaped recirculation flow at base rectangular strut, conical possessed more favorable geometry characterized by longer length, larger volume, small surface. When fueled hydrogen, equipped both could achieve self-sustaining combustion. In...
The supersonic combustor with an annular cross section has the potential to enhance fuel/air mixing because height of flow path is relatively low. However, efforts that have been dedicated this topic are exiguous. In study, numerical simulations were conducted reveal process in paths. Mach number, total temperature, and pressure entrance 2.35, 300 K, 101.325 kPa, respectively. (H) varied from 7.5 12.5 mm, but equivalent diameter was 37.74 mm for all cases. cases a jet orifice number (Nj) 8,...
Nucleoside analogs are commonly used drugs for the treatment of cancer and viral infections. deoxyribosyltransferase (NDT) is one key enzymes required biosynthesis deoxynucleotides. The feasibility biochemical transformation processes usually greatly dependent on cost biocatalysts. Therefore, immobilizing reusing biocatalysts an approach to be considered bring biotransformations closer industrial feasibility, since it not only allows reused but can also improve their stability under several...
To reduce the drag generated by recirculation flow at rocket base in a Rocket-Based Combined Cycle (RBCC) engine operating ramjet/scramjet mode, novel annular RBCC based on central plug cone was proposed. The performance loss mechanism caused and influence of configuration thrust were studied. Results indicated that extended through entire combustor, which creates an extensive range "low-kinetic-energy zone" center leads to loss. serving as surface structure had restrictive effect internal...
As a potential alternative to fossil-based fuels, cellulosic ethanol has attracted much attention due its great benefit energy sustainability and environmental friendliness. However, at present, the industrial competitiveness of production is still insufficient compared with fuels because higher costs. Expanding range lignocellulosic biomass may be promising measure promote economical ethanol. Corn fiber, byproduct from corn deep-processing, an attractive feedstock for rich carbohydrate...
The Rocket-Based Combined-Cycle (RBCC) engine integrates the preponderance of ramjet and rocket engines. It can perform excellently at a lower Mach number than while consuming less fuel rocket. higher specific impulse under flight conditions guarantees competitiveness application prospect an RBCC for reusable space transportation hypersonic cruise vehicles. With wide range numbers, flow choking between primary secondary streams in inner passage becomes complicated. not only affects mass...
The ejector mode of the Rocket-Based Combined-Cycle (RBCC) engine is characterized by high fuel consumption. This study aimed at investigating influence rocket fuel-rich degree on RBCC engine’s performance under combined with simultaneous mixing and combustion (SMC). Numerical simulations were conducted for various ratios ( <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M1"><a:mi>Φ</a:mi><a:mo>=</a:mo><a:mn>1.6</a:mn><a:mo>~</a:mo><a:mn>3.2</a:mn></a:math> ) subsonic <c:math...
Impinging-jet injectors, liquid–liquid coaxial swirl and pintle injectors are representative in liquid rocket engines (LRE). For these the atomization processes all involve impingement, including jet–jet, sheet–sheet, jets/sheet–sheet respectively. After a sheet forms fragments. Based on similarities, reviewing published literature spray characteristics of three LRE is necessary will facilitate investigation to meet progress variable-thrust LRE. This review covers following aspects...
The recent several decades have witnessed more and three-dimensional (3D) intersections in urban traffic infrastructure. Therefore, modeling road network 3D space becomes an essential step study, visualization, micro-simulation, etc. Unlike planar which roads could be simply represented by their centerlines, a line-based model tends to mislead readers, while representing with surfaces might overcome this drawback certain degree. surface built based on centerlines. However, existing...
