Spreading and adhesion properties of compressed air foam on vertical facades: Effects of gas-liquid ratio and spray angle

Key Points

• Adhesion properties of compressed air foam are significantly influenced by the gas-liquid ratio and spray angle, enhancing effectiveness.
• Higher gas-liquid ratios at specific spray angles improved foam spreading along vertical surfaces, achieving better coverage.
• Analysis of foam behavior on vertical facades highlights the critical relationship between application parameters and performance.
• Optimizing gas-liquid ratio and spray angle may lead to more efficient application methods in construction and firefighting.
