Electromagnetic transient programs (EMTPs) are widely used for simulating electromagnetic in power systems. With the increasing interest integrated energy system (IES), it would be beneficial to extend scope of EMTP-type application multi-physics transients electrical and gas networks. An efficient accurate model pipeline is proposed EMTP simulation pneumatic transients. The split into a number...

The process of hydraulic fracturing for recovery of oil and natural gas uses large amounts of fresh water and produces a comparable amount of wastewater, much of which is typically transported by truck. Truck transport of water is an expensive and energy-intensive process with significant external costs including roads damages, and pollution. The integrated development plan (IDP) is the industr...

Two phase gas-liquid flow pattern in a horizontal pipeline is predicted very accurately using a newly-developed analytical relation. The pattern identification is based on one of the most widely used graphs, the Baker diagram, modified in a way that compensates for the unrealistic oversimplifications of recent works. The Kern's method of pressure drop calculation is used to obtain the frict...
