However, leaks sometimes occur during transport, often leading to jet fires that cause substantial economic damage and property damage. It is therefore crucial to improve the efficiency of jet fire suppression.

Then a prediction model relating the horizontal length, vertical length and trajectory length of the horizontal jet flame under the action of acoustic waves is established.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90706834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key findings show that: China’s carbon pollution has a significant spatial spillover effect; the principle of joint defense should be followed to maximize the environmental benefits. There is a U-shaped relationship between tourism and carbon emission. More attentions are needed on the low-carbon development of tourism.

It is one of the most important energy sources used in the world since the 18th century. Since the 21st century, due to the massive development and mining of coal, although the value and price of coal have been lower than before, after all, coal is still one of the indispensable energy sources for human production and life for a long time. Besides, the supply of coal is also related to the stability of industry as well as the production and development of the whole society. The security of coal supply performance is also the most important part of energy security. This paper studies the coal consumption characteristics and regional distribution characteristics of typical countries in the world from 2020 to 2021, discusses the relationship between resource consumption and environmental protection, and reflects it through PM2.5 index. Through the comparison of the two data, it can intuitively reflect the environmental pollution caused by resource consumption and provide reference for the global environmental protection cause.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135429749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fractures in the deep saline aquifer enhance the heterogeneity of the aquifer, and have an important effect on CO2 migration, thus the detailed description and characterization of fractures in geological structure are very important. Existing research on the impact of fractures on CO2 migration, however, ignores the role that the fractures' characteristics play in this process. This work aims at addressing this gap. Based on the embedded discrete fractured model (EDFM), we quantified the role of the fractures in the mechanism of CO2 migration and studied the length, aperture, and orientation of the fractures. It is found that the CO2 plume takes the fracture as its preferred channel and changes the migration direction. The longer the fracture length and wider the fracture aperture, the faster the CO2 migration rate is. The change in fracture orientation mainly affects the migration direction of the CO2 plume. Due to the different angles of the plume entering the fracture, the influences on the CO2 migration rate are also different. When the orientation is 45°, the CO2 migration rate is the fastest, while it is the slowest at 135°. When there is a complex fracture network in the aquifer, the heterogeneity of the aquifer is enhanced. Compared with the non-fractured aquifer, the direction and rate of CO2 migration are greatly changed, and the instability of CO2 sequestration is increased.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82986756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Research Status and Progress of Multiples Suppression Based on Radon Transform","authors":"G. Wang","doi":"10.54097/ije.v2i2.7774","DOIUrl":"https://doi.org/10.54097/ije.v2i2.7774","url":null,"abstract":"The existence of multiple waves in seismic data has a substantial impact on earthquake imaging, inversion, and interpretation results. As a result, multiples are often suppressed as noise prior to seismic data preattack processing. Currently, there are two primary methods for suppressing multiple reflections in seismic data. One is a filtering technique based on geometric differences in the seismic waves, while the other is based on wave equation methods. The Radon transform, which suppresses multiple reflections, belongs to the class of geometric seismic diffraction filtering techniques. In the process of seismic data processing, it effectively separates multiple reflections from seismic data by utilizing the characteristic differences between primary and multiple reflections, thereby achieving noise attenuation and improving the signal-to-noise ratio of the data. This article primarily investigates the current state of methods for suppressing multiple reflections based on the Radon transform, both domestically and internationally. By introducing various forms and fundamental principles of the Radon transform, this study analyzes and compares the adaptability and pros and cons of each type of Radon transform. The high-precision Radon transform can effectively address the sawtooth phenomenon and energy dispersion issues that arise in the least-squares Radon transform. It also highlights the challenges associated with suppressing multiple reflections in the Radon transform and provides a glimpse into future developments.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87764302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
