IMPROVEMENT OF BUBBLE MODEL FOR CAVITATING FLOW SIMULATIONS

引用

Journal of Hy.rody.amics 2009年第1期21卷 41-46页

作者： TAMURA y. MATSUMOTO y. Computational Science and Engineering Toyo University Kujirai 2100 KawagoeSaitama 350-8585 Japan Mechanical Engineering University of Tokyo Hongo 7-3-1 Bunkyo-kuTokyo 113-8656 Japan

In the present research, a bubble dy.amics based model for cavitating flow simulations is extended to higher void fraction region for wider range of applications. The present bubble model is based on the so-called Ray.eigh-Plesset equation that calculates a temporal bubble radius with the surrounding liquid pressure and is considered to be valid in an area below a certain void fraction. The solution algorithm is modified so that the Ray.eigh-Plesset equation is no more solved once the bubble radius （or void fraction） reaches at a certain value till the liquid pressure recovers above the vapor pressure in order to overcome this problem. This procedure is expected to stabilize the numerical calculation. The results of simple two-dimensional flow field are presented compared with the existing bubble model.

Background: In Vitro Fertilization/Intracy.oplasmic Sperm Injection (IVF/ICSI) represents the final step in the management of Poly.y.tic Ovarian Sy.drome (PCOS). Our objective was to study.the association between PCOS phenoty.es and IVF/ICSI results in women admitted to Gy.aecological Endoscopic Surgery.and Human Reproductive Teaching Hospital (CHRACERH). Material and Method: We carried out a cohort study.with historical-prospective data collection over a period of seven y.ars (January.2016 to March 2023) at Chracerh. PCOS patients were subdivided into 4 subgroups A, B, C and D. Results: We recruited 128 patients including 64 PCOS patients divided into four phenoty.es and 64 non-PCOS patients constituting the control group. Phenoty.e D without hy.erandrogenism had used the lowest dose of gonadotropins, i.e. 1939.7 ± 454.3 IU, and had produced a greater quantity.of estradiol on the day.ovulation was triggered (6529.8 ± 4324.8 ng/ml). The average number of punctured follicles and mature oocy.es were higher in the phenoty.e D group. Ovarian hy.erstimulation sy.drome (OHSS) occurred mainly.in phenoty.e D (3/35), with an estimated prevalence of 2.3%. The fertilization rate seemed lower in the hy.erandrogenic phenoty.es A, B, C compared to the group without hy.erandrogenism without significant difference (p = 0.461). The biological pregnancy.rate and live birth rate were comparable between the different groups. Conclusion: Phenoty.e D used less dose of gonadotropins. Biological pregnancy.and live birth rates were comparable between the different phenoty.es.

The metal-organic frameworks (MOFs) have the characteristics of high porosity.and cry.tallinity. which also makes MOFs have the advantages of high sensitivity. high selectivity.and high efficiency.in the field of fluorescence sensing. It can detect the target substance efficiently.and quickly. and has excellent anti-interference. Therefore, MOFs materials are also considered as ideal materials for fluorescence sensors. This paper introduces three common preparation methods of MOFs materials: hy.rothermal/solvothermal method, mechanochemical method and microwave method. We focus on the application status of MOFs materials in the three fluorescence sensing fields of small molecules, metal cations and inorganic anions, as well as the shortcomings and improvement methods of MOFs materials in this application field. Finally. in view of the shortcomings of MOFs materials in the field of fluorescence sensing, such as poor stability. fluorescence quenching phenomenon susceptible to environmental interference, etc., it is proposed that more in-depth research should be carried out in the future in terms of anti-interference and reuse © 2024, Department of Chemistry.
