PRESSURE DROP IN GAS-LIQUID LOOPED PIPELINE SYSTEMS USING DRAG REDUCING AGENTS

Flow Pattern Identification and Pressure Drop Calculation for Gas-Liquid Flow in a Horizontal Pipeline

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...

Reducing Pressure Drop in Microscale Channel Using Constructal Theory

The effectiveness of microchannels in enhancing heat transfer has been demonstrated in the semiconductor industry. In order to tap the microscale heat transfer effects into macro geometries, overcoming the cost and technological constraints, microscale passages were created in macro geometries machined using conventional fabrication methods. A cylindrical insert was placed within a pipe, and ge...

Pressure Drop Measurements in Rectangular Micro - Channel Using Gas Flow

Due to the need for practical cooling technologies which could dissipate high heat fluxes, an experimental study of pressure drop in micro-channel was performed. In this work, laminar flow friction factors were determined using gas (air) as flow medium. Pressure drop vs flow rate data were used to evaluate friction factors in two parallel microchannels, namely MCP1 and MCP2 (1.0 mm deep x 0.240...

Looped Pipeline System for Increasing the Capacity of Natural Gas Transmission

The effect of micro/nano-particles on pressure drop in Oil pipeline: Simulation

A high pressure drop happens when heavy oil with high viscosity moves through the oil pipeline. A variety of methods to avoid this pressure drop is available. One of which is injection of chemicals to reduce the viscosity and ultimately reduce pressure drop. Using the pipesim software, the effect of dispersion of nano and micro-particles into the oil has been simulated to study the amount of th...
