Conjugate Heat Transfer Under Natural Convective Upward Inleakage of the Jet on the Obstacle of Finite Thermal Conductivity

摘要

The results of physical and numerical modeling of the upward natural convective jet over a linear heat source and conjugate convective heat transfer of its head with a massive horizontal barrier of finite thermal conductivity are presented. Liquids with different thermophysical properties and massive horizontal barriers of different thermal conductivity are considered. Considered scenarios for the development of thermo-ascending jets on the linear heat sources, depending on the Prandtl numbers and the height of the fluid layer. Numerical simulation of free convection was carried out on the basis of a dimensionless system of Navier-Stokes equations in Boussinesq approximation, recorded in variables temperature, velocity vortex and current function, by the finite element method.
