Abstract
In the present research, the effect of injection method with porous material is experimentally investigated for the high void fraction gas-liquid two-phase flow of water and steam. As well as the change of a flow pattern with the gas injection method, the effect of the non-condensable gas is experimentally investigated. And the influence on condensation heat transfer is evaluated and considered experimentally. As the results, gas phase is well fragmented by using the porous ceramics to inject the gas phase. Moreover, it is shown that the steam is condensed immediately after the gas injection point even though the gas phase include a large amount of air as the non-condensable gas.
