Fundamental and applied magnetohydrodynamics

Friday 28 Mar 2025, 09:40 → 15:00 Europe/Riga

725 ( LU Zinātņu māja)

Arturs Brekis (Institute of Physics of the University of Latvia), Imants Kaldre (University of Latvia)

This conference session, organized and lead by Institute of Physics of the University of Latvia (IPUL) is devoted to the topic of magnetohydrodynamics (MHD). IPUL has accumulated more than 75 years long experience in both theoretical and experimental research of electrically conducting media interaction with magnetic field. In this conference section researchers present their recent developments. The objective of this conference section is to provide a platform for scientists to meet and exchange ideas, especially focusing on the involvement of students involved in MHD studies.

11:20 → 11:40 Lessons learned from Japan International Fusion School 2024¶

An overview will be given about author's participation in Japan International Fusion School 2024 (JIFS). This annual event, that is organized jointly by EuroFusion and Institute of Quantum Sciences and Technologies (QST), was held in Japan, Naka site of fusion research. It gathers together 10 selected European and 10 Japanese Ph.D. students and postdocs working in nuclear fusion field and related topics, for intensive 3 weeks long educational training. This school covered all main aspects of plasma physics, liquid metal and plasma MHD, tokamak operation and diagnostics, with both praticical hands-on laboratory training, as well as lectures. The school symbolically represents the ongoing transfer of knowledge from JET to JT-60SA, which is the largest tokamak in operation, designed and built jointly by Japan and Europe.

12:30 → 12:50 Calibration of a permanent magnet EM flowmeter: numerical calculations and experiment¶

In this work, a permanent magnet EM flow meter for liquid Li at an operating temperature of 230 [C] is studied. Numerical calibration has been carried out using the results of 3D magnetic field calculations, applying them in the solid-body MHD flow approximation to the pipe, given an empirical, axisymmetric velocity profile. As a result, the potential difference and EM force are calculated depending on the flow rate. Numerical results are compared with experiment using InGaSn alloy and good agreement is obtained.
