An Analytical Investigation on CHF of Liquid Sodium Flow in Circular Channel with Four Different Mathematical Methods

摘要

This paper analyzes the experimental data of liquid sodium flow in circular channel with four different mathematical methods(ascertained mathematics、 unascertained mathematics、 gray theory and fuzzy mathematics)and gives the experimental formula of CHF. The conclusion is that the result got with unascertained mathematics method is better than those got with the three other methods. It shows that the unascertained mathematics may describe the wave characteristics of liquid sodium flow in circular channel more accurately.
