In the literature, this parameter is usually assumed to be constant and is fitted so that the calculation results correspond to the observation data. In this study under various conditions of body entry into the atmosphere, numerical solutions of the MF equations are obtained both for constant values of the ablation parameter and for a variable ablation parameter determined depending on the body size, the velocity and the flight altitude using correlation formulas previously proposed by the authors. It is studied how using a constant ablation parameter instead of a variable one affects the simulated characteristics: the meteoroid mass loss, the velocity, the energy deposition, and the trajectory, including the prediction of meteorite fall places. The applicability of a constant ablation parameter at various initial velocities, sizes and angles of entry of a cosmic body into the atmosphere is discussed.</p>","PeriodicalId":560,"journal":{"name":"Fluid Dynamics","volume":"61 4","pages":""},"PeriodicalIF":0.7,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148926583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The working performance of the scroll compressor under various axial clearances was studied, and the influence of speed and compression ratio on the internal flow field pressure, temperature, speed, and flow rate of the scroll compressor was analyzed. When the axial clearance increases, the pressure, the temperature, the flow rate, and the power of the scroll compressor gradually decrease. In the fluid domain of a scroll compressor, the pressure distribution is uniform, while the temperature and velocity distributions are uneven. As the rotational speed increases, the leakage of the scroll compressor decreases, and the coefficient of variation in the monitoring point temperature decreases from 1.6041 to 1.4301%. The coefficient of variation in the monitoring point velocity decreases from 12.7730 to 8.9128%, and the degree of the uneven temperature and velocity distributions gradually decreases; when the compression ratio increases, the leakage of the scroll compressor increases, and the temperature variation coefficient at the monitoring point increases from 1.5700 to 2.7892%, while the velocity variation coefficient at the monitoring point increases from 11.3075 to 19.9592%. The degree of the uneven temperature and velocity distributions gradually increases. Appropriately increasing the rotational speed and reducing the compression ratio can reduce the leakage of the scroll compressor and minimize the uneven gas temperature and velocity distributions in the compression chamber of the scroll compressor.</p>","PeriodicalId":560,"journal":{"name":"Fluid Dynamics","volume":"61 4","pages":""},"PeriodicalIF":0.7,"publicationDate":"2026-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148699699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
