What is the flow pattern like when a hot medium replaces a cold medium?
Thread Content
Inside a device, the medium is cooled using cooling water. During cleaning, in order to facilitate the maximum recovery of this cold medium, it is desired to replace it with a hot medium. However, in larger devices, could the hot medium flow directly upward (as it is generally assumed that hotter substances move upward), preventing the lower layers from being replaced? Or are there other patterns of flow? The mixer continues to operate during this replacement process, resulting in mixing effects; the end time for this replacement process is determined by the increase in temperature at the outlet； Everyone is welcome to share their opinions; thank you!
I can’t figure out what you mean; it would be best to draw a simple diagram to illustrate it
Simple process; this device is one with a cooling jacket, which is not shown.
As long as there is an inflow and an outflow, the cold medium will eventually be completely carried away, leaving only the hot medium behind. . . The components of the cold and hot media are different, right?
I am looking for a cryogenic medium with a lower temperature and components that are more similar to each other; it seems your view isn’t correct
