Methods for calculating the radiation angle coefficient
Thread Content
Is there any simple way to calculate the radiation angle coefficient? Please give some advice, thanks
Should the radiation angle coefficient be looked up according to some standard?
I know that when doing boiler design calculations, the boiler design manual will tell you how to carry out the calculations or where to find the necessary information
It seems there’s no shortcut; even when using software for calculations, one still has to design the structure themselves and consult tables to obtain the relevant data (including the angle coefficients), before being able to carry out the calculations. It’s quite troublesome!
Yes, it’s too troublesome; there’s no good solution
Check the table; it’s rough, but it works.
I am a student, and all I know is theory; the commonly used methods include the line integral method, algebraic analysis method, and string method. But all of them require double or triple integrals. It’s quite troublesome; the icon method would be best, but the error is quite large
The angular coefficients for each row of tubes at x=1-(1-x1)(1-x2)……(1-xn)xn can be found in Figure 5 of Appendix C2 of the calculation methods for industrial boilers
The corner coefficients can be found directly; there are relevant manuals available. You can also modify the program yourself, enter the values manually, and calculate the results, just like in those steam parameter software programs.
