![]() ![]() The foam decay time and drainage rate exhibit an exponential function distribution.ĭecay trend foam stability liquid–gas ratio temperature jump varicose veins. The half-life varies from 20 to 60 seconds.ĭecreasing the temperature jump range and liquid-gas ratio gradually enhances the foam stability. Changes in the preparation temperature yields a drainage time range of 3 to 30 seconds. The half-life ranges from 10 to 30 seconds. ![]() ![]() Comparison of the experimental and control groups shows that the temperature jump results in a drainage time range of 1 to 15 seconds. reaction vessel 3. In the entire process, the foam volume decreased with increasing drainage rate. Actinium-226 has a half-life of 29 hours. In the drainage rate curve, the temperature rose, and the liquid-gas ratio varied from 1:1 to 1:4, causing faster decay. The decay process was videotape recorded. A homemade device manufactured using the Tessari DSS method was used to prepare the foam. ![]() The experimental group conditions were as follows: mutation temperatures (10☌, 16☌, 20☌, 23☌, 25☌, and 27☌ to >37☌) and liquid-gas ratios (1:1, 1:2, 1:3, and 1:4). This study investigated the influence of temperature jump and liquid-gas ratio on foam stability to derive the foam-decay law. ![]()
