This Kirchhoff code uses calculation results from the Linearized Euler Equations (LEE) or the Large Eddy Simulation (LES) as input data. By changing the size of Kirchhoff surface, grid density and time interval between time-series data, etc., we will validate how the discretization errors, which are caused by four elements in the code, change. Also, we will check whether the errors will enter within our requirements. To understand these values pro-vides guidelines for temporal and spatial data to be output from LEE or LES calculation. In addition, some examples of practical studies using the developed Kirchhoff code are briefly introduced.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
