Embodiment Construction

[0017] The invention discloses a multi-physics field coupling microscopic seepage experiment device and method, which is composed of a computer, a bracket, a syringe pump, an optical microscope, a laser emitter, a liquid bag / air bag and the like. The fluid in the liquid bag / air bag generates pressure and flow that meet the test requirements through the syringe pump. The fluid in the syringe pump enters the seepage test sample through the silicone tube, solenoid valve, flow meter, and pressure gauge. The seepage test sample is placed on the support, and the shape of the seepage fluid inside the seepage sample can be observed through an optical microscope. The image and other data are collected into the computer through the high-speed camera installed on the microscope. The invention solves the problem that the previous microscopic seepage test can only observe the flow state but cannot obtain the fluid velocity in the seepage process.

Abstract

The invention discloses a multi-physical field coupling microscopic seepage experimental device and method. The device consists of a computer, a bracket, an injection pump, an optical microscope, a laser emitter, a liquid bag / an air bag and the like, wherein the fluid in the liquid bag / the air bag produces pressure and flow that meet the test requirements through the injection pump; the fluid in the injection pump enters a seepage test sample through a silicone tube, an electromagnetic valve, a flow meter and a pressure gauge; the seepage test sample is placed on the bracket, and the morphology of the seepage fluid inside the seepage sample can be observed by the optical microscope; and images and other data are collected into the computer through a high-speed camera mounted on the microscope. The scheme of the invention solves the problem that the previous microscopic seepage tests can only observe the flow state and cannot obtain the fluid velocity in the percolation process.

Description

technical field [0001] The invention relates to a microscopic seepage experimental device, which is especially suitable for the quantitative experimental research of the seepage flow field in college teaching and research institutes, and is an experimental device for studying various parameters of the microscopic seepage field and the flow characteristics of non-Newtonian fluid. Background technique [0002] Seepage is a very complicated process, and many flow laws need to be studied. If purely mathematical analysis is used, it is difficult to obtain correct results in most cases. Therefore, it is necessary to rely on experiments to explore laws, verify theories, and solve practical problems in production. Seepage flow field display and seepage flow field simulation are two core tasks in the development of fluid mechanics. The flow field display technology is to better intuitively understand the distribution of the entire flow field, grasp the flow characteristics, and help e...
