Abstract

The invention relates to a multi-scale heat transport synchronous monitoring test system and test method and a thermal dispersion scale effect test method. The system comprises a sand column component, a flow path assembly and a temperature sensing unit. The sand column component includes a plurality of columns filled with standard particle size porous media to simulate different aquifer structures, the sand column wall surface is a vacuum heat insulating layer formed by concentric organic glass cylinder nesting, and temperature sensors pass through the inner and outer cylindrical walls and an air layer; the flow path assembly includes a constant temperature and constant pressure control device, an instantaneous flow guide device and a drainage mechanism, the flow path assembly controls the constant temperature and constant pressure boundary conditions of the test system, the instantaneous flow guide device realizes synchronous instantaneous infiltration of fluid, and the drainage mechanism can acquire the fluid permeation flow at different periods of time; and the temperature sensing unit realizes high frequency automatic acquisition of temperature at different detection points. According to the invention, the multi-scale heat transport synchronous monitoring system can carry out semi-infinite one-dimensional convection-dispersion test of porous media with different particle size and spatial scales.

Description

technical field [0001] The invention relates to a multi-scale heat migration synchronous monitoring test system and test method. The system can simultaneously carry out half-scale testing of porous media with different particle sizes and spatial scales through functions such as instantaneous diversion, constant temperature control, lateral vacuum insulation, and automatic temperature collection. Infinite one-dimensional convection-dispersion test; through orthogonal test design, different heat source boundary, seepage velocity, particle diameter, space position and other element combination tests are screened out, and thermal dispersion scale effect is proposed through analytical theoretical derivation of thermal diffusion coefficient combined with experimental inversion calculation test method. Background technique [0002] In the field of heat and mass transfer research in porous media, the study of heat dispersion, especially the revealing of the scale effect, has always ...
