Dimensionless width k of the area around the tube sheet without tubes
Thread Content
What happens if the dimensionless width k of the area around the tube sheet where no tubes are present is greater than 1? ? What impact does it have on the heat exchanger? If the pipe spacing is not increased, the program won’t perform the calculation – can we just ignore it?
The stress condition of the tube sheet does not conform to the standards...
I see that in many cases it’s just to get the program to run, by adding certain conditions such as increasing the spacing between tubes, entering a larger value for the area of the partition slots; sometimes more heat exchange tubes are assumed to be used, but in actual manufacturing the number of heat exchange tubes remains the same, or should it be calculated using the JB/T4732 method? Increasing the tube spacing sometimes makes it impossible to fit enough heat exchange tubes to meet the required heat exchange area, which forces an increase in the cylinder diameter! ! Is there anyone skilled enough to answer?
