quenching distance

Quenching distance is the minimum space needed between two surfaces for a gas to form a continuous bubble or film when a liquid is present. Imagine blowing bubbles underwater; if two surfaces are too close, the gas can't create a stable bubble because the liquid film can't maintain itself. This distance depends on factors like liquid properties, temperature, and pressure. It’s important in processes like corrosion prevention and coating applications, where controlling gas movement and bubble formation at small gaps can influence material performance and safety.
