Title : Maintaining heat transfer functionality with vapor infusion nano bubbles
Abstract:
Heat exchangers are foundational devices used in many industries. Biological, organic, or inorganic matter in the cooling water stream may collect and adhere to heat exchange surface thus diminishing heat transfer or disrupting water flow. These foul formations may render exchangers inefficient, and in the extreme, ineffectual, thus requiring increased energy demand to operate even marginally.
- Nanobubbles can be used to enhance heat transfer through varying means such as.
- Increasing the thermal conductivity of a fluid.
- Creating wake zones that moves cooler fluids against heat transfer surfaces.
- Disrupting insulating foul formations.
- Increasing turbulence.
Nano bubbles will allow for more efficient heat transfer in applications like heat exchangers, where, due to their ability to disrupt boundary layers and create micro-convection within the fluid. When presented on a continual basis into a fluid, can lead to improved heat transfer rates compared to a fluid without nanobubbles. It will naturally reduce or eliminate the need for mechanical or chemical heat exchanger cleaning. This presentation will describe the nano bubble creation technology, previously performed studies and representative commercial applications. It will also discuss how this technology compares with currently available nano bubble generation techniques.
