The lack of a clear phenomenological model and reliable methods for diagnosing key parameters such as flow velocity, pressure dynamics, and induced current density is hindering progress in this area. This work is devoted to the preparatory stage of a comprehensive project to study such phenomena. Within the framework of this stage, key engineering and methodological tasks were solved. Numerical simulations using the finite element method were performed, which predicted the complex dynamics of the Lorentz forces. To justify the selection of diagnostic sensors, estimates of expected pressures and fluid flow rates were made based on modeling a 1.5-kA current pulse or a 0.7-T magnetic-field pulse in a uniform 1.7-T transverse magnetic field. A strength analysis of the solenoid for generating a poloidal magnetic field revealed significant mechanical stresses (up to 19 MPa), indicating the need for design modifications. The central task was to test measurement methods. The performance of piezoelectric pressure sensors in strong magnetic fields has been confirmed, and a combined measurement system using fiber-optic sensors has been proposed to improve reliability in conditions of strong electromagnetic interference. Thus, the completed engineering calculations, numerical modeling, and development of diagnostic methods formed the necessary scientific and technical basis for conducting subsequent experiments.</p>","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 3","pages":"281 - 292"},"PeriodicalIF":1.1,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147938597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of density ratio on the KHI of multi-mixing layers are also considered. The governing magnetohydrodynamic (MHD) equations are numerically solved using a validated non-splitting corner transport upwind (CTU) + constrained transport (CT) algorithm. Simulation results indicate that gravity exerts a stabilizing effect when density increases from top to bottom, which is consistent with existing research. Furthermore, increasing the density ratio gives rise to localized regions of elevated vorticity under the effect of gravity. Additionally, both transverse and longitudinal magnetic fields can significantly suppress KHI and cause vorticity deposition at mixing layer interfaces. However, unlike transverse fields, longitudinal magnetic fields induce vorticity layer separation with vorticity-free zones between separated layers, and even weak longitudinal fields exert notable effects. Furthermore, larger density ratios reduce the magnetic field strength needed to fully suppress KHI. Mechanistic analysis from the perspective of magnetic forces identifies magnetic pressure as the main cause of vorticity deposition. The magnetic tension of the transverse magnetic field exerts an anti-bending effect on mixing layer curling, while the magnetic tension of the longitudinal magnetic field forms a “magnetic tension ring” in the vorticity layer, thereby causing the separation of the vorticity layer and the formation of vorticity-free zones.</p>","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 3","pages":"334 - 356"},"PeriodicalIF":1.1,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147938791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
