Stoner Surge Model: Detailed Equations

[rppearso]

Does anyone know where to find detailed equations on the advantica/stoner water hammer surge model. The client my company is working for has hired advantica to do these water hammer cases for heavy crude and they have produced a report that makes recommendations that effect our P&ID's. I would just like to have a better understanding of what they are doing, the stamping PE is going to cloud there recommended items on the P&ID and disclaimer that he is not responsible but advantica is. When I talked to them all I got was that the stoner model was different than the method of characterization. I have looked up water hammer in perrys and bought the 2 books (fluid transients and symposium on water hammer from 1933) that were cited under the abbreviated water hammer equation in perrys. I have not had a ton of time to go throught these 2 books yet but I did notice the books went into the method of characterization but I did not see to much on the stoner method. I also learned that the stoner model was more of a finite element analysis and the method of characterization was an exact solution but only applied to simple systems.

Unfortunately, detailed equations for the Advantica/Stoner water hammer surge model are proprietary and not available in the public domain. However, you may be able to get more information on the model, as well as its application, from Advantica themselves or by reading academic papers that have used the model.

I understand your frustration in trying to find detailed equations on the advantica/stoner water hammer surge model. It is important to have a full understanding of the methodology being used, especially when it has the potential to impact P&ID's and other important aspects of your work.

I would suggest reaching out to advantica directly and requesting more information on their stoner model. It is possible that they have additional resources or documentation that they can provide to help you better understand their methods and recommendations.

In the meantime, I would also recommend continuing your research and review of the books you have purchased. While they may not specifically mention the stoner model, they may still provide valuable insight and understanding of water hammer and fluid transients.

Additionally, as you mentioned, the stoner model is a finite element analysis while the method of characterization is an exact solution. This can be a key difference in understanding the results and recommendations from each method. I would also suggest consulting with a fluid dynamics expert or conducting further research on finite element analysis to gain a better understanding of how it differs from an exact solution.

Overall, it is important to have a thorough understanding of the methodology being used, especially when it has the potential to impact your work. I hope this helps guide you in your search for more detailed equations on the stoner model.
