Christine74, thanks for your great post.

GBTorpenhow, thanks for referring to my previous threads. In fact I was trying to reopen it, but I couldn't. So, I started the new again. And also I started working in other equipment after my earlier discussion. Coming back to discussion, I agree with your image explanation, In 1-2 exchanger...

Thank you. This is my understanding of Counterflow heat exchanger working same as yours. However my question is about the Temperature cross. Also about the extract from the book. Please share your insights if you know anything about it. Thanks again for your time.

Please explain it in detail if you know the answer. Thank you.

Hello MintJulep, I don't understand your answer. Your answer is just the explanation of the counter flow heat exchanger. Also your statement "At every point along the length Thot > Tcold" is contradicting from your picture. Please have a look again. Thanks for any response related to...

Hello all! I'm new to Shell & Tube Heat Exchanger Thermal design and I have come across the term "Temperature Cross" in Counter flow Shell & Tube Heat Exchanger. What is Temperature cross in Counter flow Shell & Tube Heat Exchanger? I read in Heat Exchanger Design Handbook by Kuppan...

Hello experts! I need to design SR nozzle (hub type) and this is the first time I'm going to design it. Can anyone help me with the design guidelines of this nozzle? What should be the ID, hub thickness, hub height and bevel angle? Thank you.

Hi Andrew! Thank you so much for the explanation. I'm doing now thermal design of Shell and Tube heat exchanger. Here I have provided with temperatures & flowrates as well as heat duty to be removed from my client process team. Hence I don't have controls over the temperatures, flowrates...

Hello IRstuff, I read that Cividac website but it doesn't answer my question completely. Thats why I approached here. Can you please explain here in detail? Thank you.

Hello All, I'm currently learning S&T Thermal design, which is very new to me. In this I come to know about the Temperature cross. I do not find enough explanations in google and methods to resolve it. Can anyone please explain what is Temperature Cross and why it is happening? Also, please...

Thanks respected Latexman & Christine74. Got your point that shear stress helps to reduce fouling effect. There are no equations prescribed in my specifications. It is being calculated by Software. Also I presume that in order to achieve more shear stress, we need more allowable pressure drop...

Hello to all! This is the first time I'm going to handle Plate & Frame Heat Exchanger. I would like to know what is the importance of shear stress in Plate & Frame Heat exchanger. How it is developing the heat transfer rate? Also in my project specification, it was stated minimum Shear stress...

Thank you so much Mike.

Hi! Currently I'm taking care of Shell and Tube Heat Exchanger design and this is new to me. For the BKU TEMA type, as per project specification, Full-diameter stationary tube sheet to provided with 25% Collar bolts. I found in the calculations that Channel Side test pressure is more than the...
