This study investigates the convective heat transfer characteristics of disk-shaped biomass particles, a critical factor for particle heating and conversion in co-firing boilers that has been underexplored literature. Using particle-resolved direct numerical simulation (PR-DNS), we analyze behavior cold fluid flowing over heated disk focusing on effects aspect ratio or height-to-diameter (Ar), Reynolds number (Re), incidence angle (θ) average Nusselt (Nu). The results reveal efficiency is...
In numerical simulations of biomass co-firing in coal-fired power plant boilers, the current literature lacks precise models for drag, lift, and torque coefficients non-spherical particles. To address this gap, study develops a novel set aerodynamic coefficient correlations specifically disk-shaped particles across varying aspect ratios (0<Ar < 1), Reynolds numbers (1≤Re ≤ 2000), angles attack (0°≤θ 90°). Using body-fitted mesh method OpenFOAM, combined with direct simulation...
Abstract With the widespread applications of electric vehicles, power grid stabilization, and high‐pulsed loads, high‐power lithium‐ion batteries (LIBs) are in urgent demand. However, existing experimental‐based design is usually costly inefficient, provides limited information on complex physicochemical processes inside batteries. Digital twin concept promising for capturing batteries’ electrochemical performance, optimizing capability LIBs. Here, an electrochemical‐thermal coupled model...
Due to their high reliability, anti-interference, and power capacity, metal waveguide slot array antennas are commonly used in harsh extreme working conditions. However, the fractional bandwidth of is usually not wide enough (<20%), which limits performance microwave system. Aiming at expanding bandwidth, this letter proposes a antenna utilizing hybrid resonant structures. Five resonance frequency points simultaneously excited subtly arranged, resulting great expansion band. The measured...
The pyrolysis of pine sawdust was carried out in a fixed bed reactor heated from 30 °C to maximum 700 atmospheric nitrogen and pressurized hydrogen (5 MPa). yield, elemental composition, thermal stability, composition the two bio-oils were analyzed compared. result shows that oxygen content bio-oil (17.16%) obtained under atmosphere lower while heating value (31.40 MJ/kg) higher than those produced atmosphere. Compounds with boiling point less 200 account for 63.21% at atmosphere, proportion...
A novel vanadium pentoxide (V 2 O 5 ) nanoplatelet has been prepared by an oxalic acid assisted sol–gel method using β-cyclodextrin as exfoliation agent followed sintering at a high temperature.
