Water injection conversion efficiency of heat exchange tubes
Thread Content
Gentlemen, when cooling water is sprayed onto the surface of heat exchange tubes, is there any conversion formula for the heat transfer efficiency? Can this conversion be simulated using the HTRI software, or can it be converted into a wing aspect ratio? I’m here to ask for advice!
Important things are repeated three times! ! ! I’d like to ask everyone for advice! ! !
Thanks again! ! ! :lol
Evaporative air cooling has plenty of empirical data; when the parameter ranges are wide, the simulation errors may be significant. The evaporation rate is related to multiple factors, such as temperature, humidity, wind speed, and the surface area of the water-sprayed air film. For example, the heat transfer coefficient of an air film differs significantly between air with a humidity of 0.5 and air with a humidity of 0.8.
It seems that software vendors don’t pay much attention to simulating wet operating conditions. Some sources indicate that as long as the dry operating conditions are met, the wet conditions should also be satisfied. In the case of an evaporative condenser, spraying water on the light tubes results in mass transfer and heat exchange, which is a rather complex process
It’s very simple to calculate on your own – phase-change heat transfer! http://www.fishsting.com/
This is a bit troublesome; the original poster’s idea is quite unique – it’s worth exploring
