Accurate determination of the drag coefficient for lattice structures under turbulent skewed winds is therefore essential. This study focuses on the aerodynamic behavior of the tower body of an angle steel lattice transmission tower. Through wind tunnel tests and CFD simulations, the aerodynamic force coefficients of the lattice structure were investigated under different wind speeds, solidity ratios, and wind flow fields. A novel calculation formula for the skewed wind load factor of lattice structures was proposed through regression analysis of experimental data. The proposed formula was compared with recommendations from current standards. Additionally, turbulence influence factors and specific angle factors were introduced to quantify the effect of turbulence intensity on the drag coefficient of the lattice structure. The results indicate that the new skewed wind load factor calculation matches well with experimental results and the skewed wind factor can be derived from the solidity ratio. The drag coefficient of the lattice structure increases with rising turbulence intensity. Both the turbulence influence factors and specific angle factors effectively capture the effects of turbulence intensity on the drag coefficient, exhibiting a linear relationship with turbulence intensity.</div></div>","PeriodicalId":54752,"journal":{"name":"Journal of Wind Engineering and Industrial Aerodynamics","volume":"264 ","pages":"Article 106134"},"PeriodicalIF":4.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144204275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, an impinging jet flow model was used to simulate the downburst wind field, and nonlinear least-squares fitting was applied to obtain vertical wind velocity profiles from the simulation results. Then, these profiles were combined with inlet conditions to induce sand movement, creating a sandstorm environment. Finally, the discrete phase model (DPM) was applied to analyze the effects of radial distance and sand particle diameter on the HST aerodynamic characteristics. The results indicated that sand concentrations initially increased and then decreased with radial distance, while they consistently increased with larger particle diameters. Since the effect of crosswinds played a dominant role, variations in the pressure coefficient were more sensitive to radial distance than to sand diameter.

Therefore, it is of great significance to study disaster control and loss reduction after coal-gas outburst. Previously, there were fewer studies on airflow oscillations in open-loop systems in coal mines. Comprehensive use of theoretical analysis, experimental analysis, and numerical simulation to study the oscillatory behavior of airflow in coal mine open-loop systems. Control equations for an idealized open-loop branching system are defined, and a numerical analysis method that considers dispersion and mixing at the air-methane interface is developed and validated against a physical model. This study derives the oscillatory behavior of airflow caused by gas wind pressure in upward ventilation of parallel inclined roadways. Using modeling to parameterize the effect of initial airflow velocity of stagnant methane in upward ventilated roadways containing parallel branching roadways, the conditions for controlling the phenomenon of oscillating airflow in such upward roadways were simulated, and it was concluded that when the phenomenon of airflow oscillation occurs in parallel upward ventilated systems, the number of airflow oscillations is significantly reduced by increasing the initial airflow velocity. The amplitude of each oscillation is reduced. When the initial wind speed was 0.2 m/s, several wind flow reversals and airflow oscillations occurred. When the initial wind speed increased to 0.35 m/s, two wind flow reversals occurred, and the maximum wind speed difference after the reversal was 0.2 m/s. At an initial wind speed of 0.5 m/s, a single reversal of airflow was observed, but no oscillatory behavior was noted. After the reversal, the maximum wind speed difference was 0.16 m/s, and the maximum wind speed difference was 0.16 m/s in the range of 0.5 m/s-0.65 m/s. The difference in the reversal was 0.12 m/s.

Thirty three ulcers failed to achieve 50% size reduction, after the 4-weeks standard care, and were allocated to be treated with: HBOT plus venous intervention (n = 17), or venous intervention alone (n = 16). Primary outcomes were the change in ulcer area, complete healing frequency and time, as well as ulcer recurrence. There was a history of recurrent ulcer (82.3% vs. 69%) in HBOT versus venous intervention groups, respectively. The comparison between both groups with regard to area change showed non-significant difference after 3 months of therapy, while there was a significant difference at 6 and 12 months. A significant positive correlation was found between the HBO sessions numbers (20-40) and the rate of ulcer size reduction. Ulcer complete closure after 3 months was observed in (41.7%) of HBOT group, versus (23%) in venous intervention group; (p = 0.33).

Accordingly, rapid risk assessment of long-span bridge buffeting performance at multiple levels is needed. To this end, a closed-form solution is developed in this study by convolving the wind hazard function (fitted as a polynomial curve) with the structural fragility function (fitted as a lognormal curve) for risk evaluation with high efficiency.

To verify the efficiency and accuracy of the proposed approach, the buffeting risks calculated by the closed-form solution are compared with those obtained through the Monte Carlo simulations.

Furthermore, thermal stratification can influence higher-order turbulence statistics near the surface under strongly unstable conditions, but the overall statistical patterns tend to exhibit universal behavior.
