Rahul Ji how to do gas pipeline surge analysis in hysys software

Von Loaf

Thanks for your content sir could u please make a detailed video on it

You're explanation are far better fhan anyone on UA-cam 😊

Please continue this series sir

Nice Explanation.

HYSYS family is a thermodynamic based simulator where it uses Bernoulli's Equation to solve the hydraulic calculation. However, please note that the momentum factor is not account in both steady-state and dynamic solvers which is important in the hydraulic transient study. The results shown may not reflect the actual pressure surge phenomenon and ultimately, not able to capture the max.pressure/ highest peak during the surge event. That's part of the reason why surge study is preferably carried out on other simulators like PIPENET, AFT, etc instead. Just my honest opinion.

I kept this calculation on hold as I had no idea how to show water hammer in pipeline.. thanks a tons

Hi Rahul, thanks for great video. This enlight me on dynamics of pressure rising. However in my case pressure is not rising when I keep VLV-100 full open and VLV-101 full close. what is the boundary PF-specification? whats the stream<1> has Pressure or flow specification and stream <4> (<4> understood to be Pressure spec of 49.3 bar). Moreover, could you please advise where may go wrong with my sim. Best Regards.

Sir is it Conval.software??

U explained this concept in a very comprehensive way. Thanks a lot for clarifying my doubt.
