Exchange Heat Heat exchange

AI Thread Summary

Enamel paints suitable for heat exchangers should minimize heat loss while allowing effective heat transfer. The heat conductivity of paints is often not specified, making it challenging to select the right product. It is noted that the thickness of the paint layer, typically a few micrometers, is unlikely to significantly impede heat transfer. Users should consider the thermal properties of the paint when making a selection. Ultimately, choosing the right enamel paint can enhance the efficiency of heat exchange systems.

Hey,

What type of enamel paints is suitable to paint the tube bundle in heat exchange so that it allows heat transfer (minimize heat loss in the paint)? heat conductivity is not usually mentioned in paints specifications.

Thank you ..

Conductivity is usually of inverse linear dimensions. A few micrometers shouldn't reduce heat transfer much.

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
