Quantitative Water Temperature Field Analysis On ANSYS

Because of the specialty of high energy physics cosmic ray projects,the testing ground should be on high altitude places,such as the project As? conducted by China and Japan,and the project ARGO(Tibet Yangbajing)conducted by China and Italy.However,the high altitude places are cold and permafrost regions,which brings great challenges to the experiment project heat preservation,how to achieve heat preservation and reduce heat preservation cost is the top priority of the project.This paper is based on the project LHAASO's sub-project Muon detector.And after long-term observation,in consideration of temperature,climate and environment,various temperature's data of the air and different depths of soil layer is measured.Multiple temperature function is fitted out using MATLAB and geometric model is set up using ANSYS,and then the function is applied to the model getting the changing temperature of the water in the detector,after which we compare the result with that measured in the experiment to verify the feasibility of the simulation method which should be used on the water body in the project LHAASO to get the proper insulation layer material and thickness in consideration of the balance between the economy and adaptability.The main research contents include the following parts:(1)Theoretical analysis of ANSYS simulation and estimation of the thickness of insulation layer.(2)Through the long-term monitoring of the experimental model,the temperature function of the air layer and soil layer is fitted.(3)According to the Yangbajing climatic conditions,the use of ANSYS modeling and data analysis of water temperature field.(4)The ANSYS simulation data and measured data were compared,and the feasibility of the simulation model was analyzed.(5)The index requirement of the material and thickness of the Muon detector is put forward,laying the foundation for the smooth construction of the Muon detector for the LHAASO project.
