How to enter the actual number of trays during tower simulation?
Thread Content
I have a question: when simulating the operation of a tower in a factory, is it necessary to enter the actual tray information directly, or how is the tray efficiency set? (Please ignore the thermodynamic equations for now.) What is the impact of directly entering the tray geometry on the accuracy of the simulation?
Generally, it is done by directly entering the actual number of trays, and then setting the tray efficiency value.
The tray efficiency is used; by multiplying the actual number of trays by the tray efficiency, the theoretical number of trays is obtained. During simulation, this theoretical number of trays is simply entered, which makes the calculations converge more easily~
So after doing this calculation, how do you present the design requirements to the tray manufacturer? Won’t the number of trays be reduced then?
Aren’t you considering the plate efficiency? Now that you know the theoretical plate number, don’t you know how to convert it into the actual number?
In this way, the number of plates can be determined, for example 10. But when submitting this information to the plate manufacturer, what if the gas-liquid data for each plate, obtained from the software, corresponds only to 8 plates? . If the efficiency is 0.8.
The simulation value is 8*0.8; it works whether starting from the 6th or 7th block. Do you think the error is significant if one block is omitted?
The number of boards you enter is considered the actual number of boards
It makes little difference in terms of the manufacturing process, but it represents a lot of waste in terms of money. A board seems to be quite expensive.
