WebPhysics of Choking. Choking can happen when a fluid is discharged through a passage from a pressurized chamber into a chamber that is at a significantly lower pressure. When a flow passage is choked, it supports the maximum possible fluid discharge rate for the given system conditions. Choking can be better understood by the simple experiment ... WebABSTRACT High pressure pipeline transportation has been an established technology for economically transporting large amounts of CO2.However,there are still issues and associated risks that have to be effectively addressed and adequately understood.It is well known that a strong Joule-Thomson Cooling effect can occur when pressurized CO2 … hoa leans
