In industrial process engineering, aeration is a vital unit operation that involves the uniform dispersion of the gas phase into the liquid phase, maximizing mass transfer (absorption or desorption). Absorbing gas into a liquid to trigger a chemical reaction is often a critical responsibility. Occasionally, the gas simply provides energy via buoyancy for mixing the liquid. Aeration in reactors plays an essential role in many processes across the water treatment, chemical, pharmaceutical, and biotechnology industries.
By employing CFD simulations, we can analyze crucial process parameters, such as:
- Gas distribution throughout the system
- Total gas hold-up
- Mass transfer rate
- Mass transfer efficiency
- Size distribution of bubbles
Fine bubble aeration is an optimal method for enhancing the contact surface between the gas and liquid phases, resulting in a higher mass transfer rate.
In some applications, fine bubble diffusers may be impractical to install or may demonstrate poor efficiency. In these cases, coarse bubble aerators are installed. Moreover, coarse bubble aeration systems are an effective solution for adding turbulence and mixing within the system.
