Hey,
I am currently making a master thesis concerning water hammer on an adblue network.
But I require the fluid properties of this urea water solution.
Thank you very much,
P. Fédor

Hi @fplatteau,
do you intend do make a CFD simulation to achieve this or what do you have in mind?

Yes,
That is correct. But I require the bulk modulus of the urea water solution.

Hi again @fplatteau,
I am not an expert in this but could you not just use this formula:
where
Rho = Density of the fluid [kg/m³],
K_f = Bulk Modulus of the fluid [N/m²],
E_R = Young’s Modulus of the pipe [N/m²],
d_i = Inner diameter of the pipe [m],
s = Thickness of the pipe [m]
mu = Poisson’s ratio of the material
Assuming that the Bulk Modulus is the unknown you could simply rearrange the formula, can’t you?
Tell me if I am mistaken.
Source of the formula: Druckstoß - Wikipedia

Hey Jousefm,
Thank You very much for the information. But to use the formula, I require the wave celerity before I can calculate the Bulk modulus. I found on the internet by searching on topics related to modelling of SCR techniques with adblue, a paper with a graph containing the information required.
So I would like to thank you for your help and interest.
Yours sincerely,
Platteau F.
Hi @fplatteau,
Do you have another approach for this then? I also found a few papers about these SCR techniques. What was the information that was missing? Just the celerity then?
Cheers,
Jousef
