תאור
הפרוייקט:
Finite element (F.E.) thermal modeling of structures subjected to complex flow regimes requires knowledge of the heat transfer interaction between them and the surroundings and between themselves (radiation). The thermal interaction is modeled by proper definition of convective and radiation boundary conditions. CFD software allows for automatic determination of the convective boundary conditions. Such an approach usually results in models, which are very complex to build and demands long solution times. On the other hand, in many occasions, we can avoid building a CFD model by calculating these boundary conditions based on our physical understanding of the problem. The goal of this project is to write a “thermal expert wizard” that will calculate and apply the necessary boundary conditions as a function of time, space and flow regime, thus saving modeling time and improve the accuracy of the results. Development and verification of this “thermal wizard” will be carried out using available tools of the commercial F.E. computer program ANSYS.
