| In recent years,our country develops so fast that it becomes an industrialized country and at the same time,air pollution is becoming more and more seriously,energy conservation and emissions reduction has been took more and more attentions.The emissions of carbon dioxide has caused attentions all over the world,many researchers and scholars in the field which related to the emissions of carbon dioxide constantly explore and research.The Carbon Capture and Storage(CCS)technology involves three parts,we should take consideration of how to capture carbon dioxide,how to transport it and how to storage it.In order to save the cost of carbon dioxide transportation,we decide to transport carbon dioxide in the form of liquid in the pipe,but due to long distance of pipelines,it will loss pressure,change temperature inevitably,and then carbon dioxide will change from gas phase into liquid phase and finally exist in the form of gas-liquid two phase fluid.In order to control the transportation accurately there is a need to know about the state of fluid in the pipeline,the state parameters of carbon dioxide gas liquid two-phase fluid need to be measured.Through to do many researches about the carbon dioxide gas liquid two-phase flow void fraction measurement methods in this article,there is a sensor device of the carbon dioxide gas liquid two phase fluid porosity real-time detection design by mathematical ray absorption principle,at the same time the corresponding static experimental project was designed to validate the feasibility of the principle and obtained the experimental datas under various temperature.The relationship between temperature and linear absorption coefficient of liquid carbon dioxide was found by analyzing the experimental data.The experimental apparatus in this static experiment is designed by myself and the experimental system is provided by the nuclear energy and new energy research institute of tsinghua university. |
