Physical Vein Models to Quantify the Flow Performance of Sclerosing Foams

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
Foam sclerotherapy is clinically employed to treat varicose veins. It involves intravenous injection of foamed surfactant agents causing endothelial wall damage and vessel shrinkage, leading to subsequent neovascularization.

Experimental study on mass loss mechanism and cooling effect of compressed air foam on fuel surface at different temperatures

open access: yesCase Studies in Thermal Engineering, 2023
Compressed air foam (CAF) is widely used as a high-performance extinguishing agent for liquid fuel fire. In this work, the effects of initial fuel surface temperatures (50–80 °C) on the drainage and evaporation of CAF were studied experimentally.
