11. Summary of the new findings of the thesis

- In the two-dimensional case, some types of movement of the flow were discovered, including steady motion, periodic motion or quasi - periodic motion.

- The thesis  has been shown the quantify  effects of two different types of boundary conditions on the effectiveness of ventilation.

- In the three-dimensional case, some types of movement of the flow as in the two-dimensional case were found. In previous publications, the authors have shown the existence of steady and periodic flow, but the thesis has detected the quasi – periodic flow.

- Simulation of ventilated problems with different locations of inlet and outlet was conducted to evaluate the effect of heat transfer or contaminant in the box.

12. Paratical applicability, if any:

 The results of the thesis when applied to specific spaces can be used to refer to the design of buildings or factories.

13. Further research directions, if any

- Complete the software developed in the thesis to be more flexible in orenting the pratical application of research contents.

- Develop closer models with realities (taking into account tangle property) when the ventilated flow is larger

- Develop the corresponding software that applies perallel computing technology on high – capacity computer systems that may be equipped in the future.
