You might want to consider having multiple inlets spaced down the plate and turn them on sequentially to approximate the situation in a transient solution.
That sounds like a cool workaround.
The problem is that in this case it might not give an accurate answer. I calculated that the plate moves for 23 seconds, which is a very short time.
Say for instance the first blower has operated for 2 seconds and the body has cooled down by 10 degrees in the portion near the blower. I doubt that the portion of the body under the second blower will already have "felt" that temperature decrease, therefore the portion of the body under the second blower will start with the initial body temperature or something near.
I will think about some methods to improve your idea. Maybe boosting thermal conductivity for a fraction of time in order to transfer temperature field under the first blower to the whole plate, and then change thermal conductivity to its original value.
With your workaround idea, your fld becomes your export and initial conditions. Go into the general settings and then initial conditions and it will allow you to choose the fld as the initial conditions of your second analysis. You're going to have to do some serious testing in this method. Both this method and bills is a stretch of the software's capabilities. Keep us posted on how things go.
I've found another method that is based on a flow rate variation curve over time:
- set a certain flow rate for a certain amount of time (e.g. 4 seconds)
- make a very low flow rate for an amount of time (e.g. 2 seconds)
- put again the flow rate to its maximum for another 4 seconds
This works almost like having a blower that turns on and off, or the plate approching another blower while moving.
certainly could work as long as you're ok with the assumption that it isn't important that the plate isn't coming with any heating. in your method, its close but not really what you described originally.
