Original abstract

The reason why to deal with mathematical model of tee-junction is to find a way how to treat the tee-junction as a pipe-line net element. The current mathematical models Kenji [3] are rather simple based on wrong assumptions and useless for our purpose. The new mathematical model of tee-junction will be showed in this article. This model is possible to use for unsteady fluid flow. The only problem is to determined so-called substitute length of branches of tee junction which appears in unsteady terms of the mathematical model. The first approaching how to set these substitute lengths and first results based on the numerical modeling of fluid flow in the tee-junction will be introduced in this article.
