Studying the unsteady conjugated heat exchange when filling a pipeline with liquid metal

Creators

Description

Unsteady conjugated heat exchange when filling a pipeline with a liquid metal is investigated. A set of two nonstationary differential equations of energy in partial derivatives of the elliptic type for a solid channel wall and for the liquid metal flow is solved. Dynamics of the temperature field in the channel wall and in the liquid flow is obtained. Nusselt numbers Nu are shown to be closer to specification of boundary conditions T=const, than to specification of boundary conditions q=const (T-temperature, q-heat flux). 7 refs.; 16 figs
