A Mesh Automatic Generation Method Applied to Thermal Design of Temperature Control Box

Abstract

The invention discloses an automatic grid generation method applied to thermal design of a temperature control box. The automatic generation method for a grid with relatively high quality is suitable for three types of existing temperature control boxes (a rectangular temperature control box, an arched temperature control box and a rectangular and trapezoidal temperature control box), any size of a box body, any position and size of an air inlet and an air outlet of an air conditioner, any position and size of a controlled object, any grid quantity and near-wall Y+ requirements. The method comprises the steps of performing classified grid recording according to three steps to generate scripts; constructing an XML (Extensive Markup Language) text data frame; reading text data and judging that which of script combinations is used specifically; processing the data and then assigning values to the corresponding positions of the corresponding scripts to realize script data rewriting; reading the text data, estimating the heights of first-layer grids at different near walls according to the Y+ requirements and related physical property parameters, and performing rewriting in the corresponding positions of the selected scripts; and calling and running the selected script combination. An input condition is random; one-button type grid generation is realized; and the demands of the fully structured grids at the near walls are met, the boundary capture is accurate, reliable and controllable, and the grid with the relatively high quality can be provided for computational fluid mechanics.
