激光辐照下双层钢板接触界面对传热的影响
Effect of two steel plate’s interface on heat transfer under laser beam irradiation
-
摘要: 首次提出激光辐照下双层金属板界面会由于变形而产生脱离，从而对双层板之间的传热有明显的影响，通过实验和数值模拟验证这一提法。该工作丰富了接触热阻概念，有助于进一步加深对强激光破坏机理的研究，同时提供了一条有效的抗强激光加固的途径。Abstract: In this paper, it is supposed that there is a gap in the interface of two contacting steel plates due to thermal deformation under laser beam irradiation, and this gap will affect heat transfer in this interface obviously. This supposition is testified by experiments and simulation. This work is helpful to the study of the destruction mechanism under high power laser loading, and provides an effective way for anti-laser research .
