Other AbstractThe behaviors of liquid drops in microgravity have been experimentally performed in Beijing 3.6 s Drop Tower. Contact angle dynamic behaviors of sessile and pendant liquid drops on PTFE and Aluminum were measured and analyzed for varying Bond number. It was found that Bond number had direct influence on the drop contact angle. And the drops with different status (sessile or pendant) also exhibited dissimilar contact angle behaviors when Bond number closed to zero. For comparison, the VOF methodology was introduced to analyze numerically the influence of Bond number on the shapes and inner bulk flow fields of liquid drops. It indicated that the bulk flow could influence the shape and contact angle of drops evidently.
