| Title of the article | Selection of mathematical model to describe the thermal process of the laser welding of spring-twisted channels |
| Abstract. | Modeling of physical processes of laser welding speeds up the solution of optimum processing conditions with the help of computer technology. The same mathematical simulation reduces the cost of implementation of the experimental work. Mathematical models of the thermal conductivity of the process with the appropriate boundary conditions. There are several methods for detecting the heat equation. They differ from each other in the accepted system of coordinates, and as a source. This article deals with the choice of a mathematical model describing the heat of the laser welding for the production of spring-twisted-channel heat exchangers, which are the basic element of high-performance shell and tube heat exchangers of the new generation. Dependence of thermal cycles and graphs based on experimental studies conducted with data. Found that for the construction of more precise mathematical models must take into account the form of blanks, which greatly complicates the process of model building, but will allow higher quality modes to choose laser welding. |
