Abstract
A new type of flow visualization method with helium bubbles has been developed. This method is based on the ordinary helium bubble method which uses soap bubbles filled with helium gas. The bubbles are injected into the flow in front of the body or injected into the separated region directly. The traces of bubbles are photographed twice in a proper interval. The velocity vectors are calculated by measuring the distance between two traces of each bubble.
