CN105492895A 用于确定绕流的面上的壁剪切应力和/或转变点的方法和测量设备 无效 - 驳回

用于确定绕流的面上的壁剪切应力和/或转变点的方法和测量设备
摘要：
本发明涉及一种用于借助于热摄影术确定绕流的面(1)上的壁剪切应力和/或转变点的方法，其中该方法包括如下步骤：在要绕流的面(1)上提供具有隔热层(3)的表面，对要绕流的面(1)进行绕流，加热绕流的面(1)，借助于摄像系统(7)无接触地测量绕流的面(1)的输出的流动强度，确定绕流的面(1)上的至少一个温度衰减系数并且求得绕流的面(1)上的壁剪切应力和/或转变点。本发明还涉及一种用于确定绕流的面(1)上的壁剪切应力和/或转变点的测量设备和/或涉及到流中的热传递的定性的显示。
摘要（英）：

The invention relates to a method for determining a transition point and/or for determining wall shear stresses on surfaces (1) around which surfaces a flow circulates by means of thermography, wherein the method comprises the following steps: providing a surface with a heat insulation layer (3) on the surface (1) around which a flow is to circulate, circulating a flow around the surface (1) around which a flow is to circulate, heating the surface (1) around which a flow circulates, contactless measuring of the emitted flow intensity of the surface (1) around which a flow circulates by means of a camera system (7), determining at least one temperature decay coefficient on the surface (1) around which a flow circulates and ascertaining the transition point and/or the wall shear stresses on the surface (1) around which a flow circulates. The invention further relates to a method for determining a transition point and/or for determining wall shear stresses on surfaces around which a flow circulates and/or the qualitative representation of the heat transfer into the flow.
