Statistical design of experiments as a tool for investigation for the influence of porous coating on the critical heat flux

Abstract This paper presents the results of a detailed characterization of critical heat flux (CHF), obtained using a design of experiments (DOE) methods. The results show that the operational behavior of a CHF is mainly influenced by four independent input variables. The influence of the porous coated tube on critical heat flux (CHF) is investigated. At first, there were 4 variable input factors included in the process. Only some of them have dominant effect on CHF. More exact relations, between mass flux, pressure, presence of porous coated, L/D and critical heat flux were investigated. The effect of a measurement error was also detected.
