摘要

To measure contact angle between CO2 and solid surface,in this study a visual high-pressure vessel has been developed,with a corresponding well-controlled constant temperature system.Pendant drop method is applied to the investigation of the contact angles of CO2 on a stainless steel surface in its own vapor.The image of the pendant drop is recorded by a camera,and a B-Snake method is used to analyze the contour and the contact angle of the droplet.The experimental results have provided a set of well tested data,which show that CO2 has good infiltration into stainless steel surface and the de-veloped method can be used as a standard testing one for measuring the contact angle between high-pressure liquid and solid surface.
