A steam injector which consists of a compact structure has high heat transfer performance due to the direct contact condensation. And it is expected that the feature to drive without any rotating power source and act as a static jet pump may enable to reduce the total system energy. Therefore it is suggested to useful for application to the small energy equipment. The objective of the present study is to investigate the operating characteristics of an ultra micro steam injector (UMSI) whose throat diameter is 600 pm from the flow observation as the first stage of the development of the further small SI. The flow structures were compared with changing the flow channel geometry. As the results, the water jet was formed at the center of the mixture part regardless of the presence of the drain and the flow channel geometry. It was confirmed that the flow structure was different due to the flow channel geometry. There is the steam condition that it becomes negative pressure in the mixture part by setting up the drain and the check valve.
