Numerical and experimental study of liquid metal stirring by rotating permanent magnets

In this work, we study liquid gallium stirring by rotating permanent magnets. We demonstrate possibility of easily creating different flow patterns by rotating permanent magnets, which can be industrially important for controlling heat and mass transfer processes in the system. Unlike the typical approach of simulating magnet rotation as a transient problem and time-averaging the Lorentz forces, we solve the magnet rotation as a harmonic (frequency domain) problem, which leads to forces equal to time-averaged ones and decreases the simulation time considerably. Numerical results are validated using qualitative flow structure results from the neutron radiography visualization of tracer particles and quantitative data from Ultrasound Doppler velocimetry

VET ecosystems and labour market integration of at-risk youth in the Baltic countries: implications of Baltic neoliberalism

The paper seeks to disclose the features and implications of the neoliberal VET and employment policy agendas for the social and institutional VET ecosystems and the integration of at-risk youth in the labour market in the Baltic countries. The research is based on the comparative policy analysis approach with reference to the theories of social and skill formation ecosystems and the historical institutionalism perspective. The research has revealed three interconnected and alternately/simultaneously applied development pathways in the skill formation and vocational education of at-risk youth in the Baltic countries: (1) the market-oriented approach based on fostering immediate employability based on the momentary skills needs in the economy; (2) the state-assistance approach based on ensuring equal access to the VET and employment services by the state and (3) the approach of systemic support to socially disadvantaged or at-risk young people in developing their capabilities
