许多技术问题是由于冰粘附到冷却固体壁（表面）而引起的。因此，迫切需要阐明冰粘附的机理。人们认为，冰对冷却壁的粘附是由冰与壁之间的传热和界面现象控制的。在这项研究中，测量了与每单位面积的粘附力相对应的剪切应力，以从壁表面去除冰，以及一些试剂在壁和冰上的接触角，改变壁材料及其表面状态。此外，分别通过剪切应力和接触角计算从壁表面去除冰的剪切功以及壁和冰的表面能。并且还通过计算的表面能计算了冰与壁之间的界面处的粘附能。然后，讨论了传热和界面现象对冰粘附的影响，以阐明冰粘附的机理。 (c) 2006 Elsevier Ltd 和 IIR。版权所有。
Many technological troubles are caused by ice adhesion to a cooling solid wall (surface). Therefore, it is urgent to clarify a mechanism of ice adhesion.It is thought that ice adhesion to the cooling wall is governed by heat transfer and interfacial phenomena between ice and the wall. In this study, shearing stress corresponding to adhesion force per unit area to remove ice from the wall surface and some reagents' contact angles on the wall and ice were measured, varying the wall material and its surface state. Moreover, shearing work to remove ice, from the wall surface and surface energies of the wall and ice were calculated by the shearing stress and contact angles, respectively. And adhesion energy at an interface between ice and the wall was also calculated by the calculated surface energies. And then, influence of heat transfer and interfacial phenomena on ice adhesion was discussed to clarify the mechanism of ice adhesion. (c) 2006 Elsevier Ltd and IIR. All rights reserved.
