摘要

本文提出了一种分析方法,用于明确计算被高斯移动热源加热的固体的三维和瞬态温度。移动热源在固体照射表面附近的薄层中散热,可以是恒定的,也可以是脉冲的,还可以是任何时间演化的,具体取决于应用。求解结果只需要一个随时间变化的收敛积分,可以使用商业形式计算软件等进行快速数值计算。另一方面,温度相对于时间的导数是完全显式的。我们的研究表明,所开发的分析解决方案与我们在相同条件下进行的数值建模结果非常吻合。我们对温度演变和热图进行了展示和评论。

Thermal Behavior of Solid Heated by Gaussian Moving Heat Source
In this paper, an analytical development is proposed to explicitly calculate the three-dimensional and transient temperature of a solid heated by a Gaussian moving heat source. The moving source dissipates heat in a thin layer near the irradiated surface of the solid and can be constant or pulsed or have any time evolution, depending on the application. The resulting solution requires only one convergent integral over time, which can be quickly computed numerically using, for example, a commercial formal calculation software. On the other hand, the derivative of the temperature with respect to time is fully explicit. We show that the results of the developed analytical solution are in excellent agreement with those of a numerical modeling that we performed under the same conditions. The temperature evolutions and the thermal maps are presented and commented.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
