“…And experimental data on changes of stagnation parameters over time in the process of dynamic leakage of hydrogen were lacking. Studies on the propagation law of flame upstream and downstream in the turbulent hydrogen jet were rare, and systematic quantitative analysis of flame propagation velocity was lacking [21][22][23][24][25]. This paper focuses on the weak points of current research.…”

Hydrogen is promoted as an alternative energy given the global energy shortage and environmental pollution. A scientific basis can be provided for the safe use and emergency treatment of hydrogen based on hydrogen leakage and combustion behavior. This study examined the stagnation parameters of dynamic hydrogen leakage and flame propagation in turbulent jets under normal temperatures and high pressure. Based on van der Waals’ equation of state for gas, a theoretical model for completely predicting stagnation parameters, outlet gas velocity, and flow rate changes in the process of high-pressure hydrogen leakage could be proposed, and the calculation result of this model was compared with the experimental result, with an error within ±10%. The progression and propagation of the flame in turbulent jets after ignition were recorded using the background-oriented schlieren image technology, and the propagation speed of flame from the ignition position downward and upward was calculated. Moreover, the influence of initial pressure, nozzle diameter, and ignition position on the flame propagation process and propagation speed was analyzed.

“…Therefore, multi-criteria decision-making (MCDM) approaches were considered by various scholars for criteria weighting and alternative ranking [3]. For instance, AHP and DEMATEL methods were used with the aim of finding the SWARA model was also considered for the same purposes [6]. On the other side, some researchers also used TOPSIS and VIKOR models to rank alternatives [7,8].…”

Green energy projects contribute to sustainable economic development of countries with the employment of environmentally friendly energy production strategies. However, environmental priorities should be examined for this situation. Therefore, priority analysis should be executed for the environmental issues while implementing green investment projects. Accordingly, this study aims at proposing a unique decision-making model based on orthopair fuzzy sets and the golden cut degrees for the environmental priorities of green project investments. The main novelty of the study stems from its proposed integrated model by equipping the Multi-SWARA, and TOPSIS based on the q-ROFSs technique with the golden cut. A set of criteria is identified for measuring the green projects' environmental priorities while several project alternatives are also determined with the supporting literature. Appropriately, the extensions of Multi-SWARA and TOPSIS methods have been applied for weighting and ranking the factors, respectively, in the integrated approach. Additionally, a comparative evaluation is performed with the help of VIKOR method to rank the alternatives. Besides, the sensitivity analysis is applied to illustrate the coherency of the weighting results in the decision-making approach. Accordingly, 5 cases are considered to measure the effects of changing weight results. It is defined that this model is coherent and could be extended for further studies. It is concluded that the reduction of emissions is the most essential item for the environmental priorities of green project investments. Pollution control, waste management and eco-friendly transportation activities are the most critical alternatives. Therefore, this study recommends that investors of green projects should prioritize the strategies of minimizing carbon emissions problem. In this context, investing in renewable energy technologies will help green project investors solve this problem.

Summary Nowadays energy demand has increased due to industrial development and population growth. On the other hand, attention to environmental issues has made it necessary to use renewable energy. The utilization of wind energy is emphasized due to low construction costs and rapid installation. Wind energy, on the other hand, can be stored via creating hydrogen because its power fluctuates at different times and is not uniform. The production of hydrogen and energy is essential to meet the needs of industries in different countries. Therefore, in this study, a comprehensive approach is presented to locating hydrogen production from wind energy using multicriteria decision‐making (MCDM). To implement the proposed approach, a case study in Iran and Hormozgan province is used. Hormozgan province is in good condition in terms of wind potential and many industries in this province need energy and hydrogen. The most appropriate factors were judged to be average wind speed, each region's number of refineries, and each region's rate of industrial development, with weights of 0.192, 0.167, and 0.141, respectively, using the stepwise weight assessment ratio analysis (SWARA) approach. The cities in Hormozgan province were then prioritized using the weighted aggregated sum product assessment (WASPAS) technique. Then, the sensitivity analysis of the ranking results was performed and The COmplex PRoportional ASsessment (COPRAS), additive ratio assessment (ARAS), and weighted sum methods (WSM) methodologies were then used to validate the results. For the development of hydrogen projects, Bandar Abbas was determined as the most suitable place. A 900‐kW turbine at Bandar Abbas will generate 532 730 kWh of power and 8620 kg of hydrogen annually.
