Pressure transients in conduits such as pipelines are unsteady flow conditions caused by a sudden change in the flow velocity. These conditions might cause damage to the pipelines and its fittings if the extreme pressure (high or low) is experienced

Air/surge vessels protect water pipelines during pressure transients. A Rational Heat Transfer (RHT) model and Polytropic ( P V n = C ) model exists for predicting the thermodynamic behaviour of the enclosed air in the vessel during pressure transien

An important choice that Coal fired power plant (CFPPs) designer needs to make is the final feed water temperature (FFWT) as well as extraction pressures from the turbines which supplies heating steam to the heaters. Different methods have been repor

A constant CO2 emissions factor in energy mix models is often used when trying to show the CO2 emissions reduction benefit in deploying a large amount of renewable power on the grid. This approach is flawed due to its inability to capture the impact

The main steam condenser is an essential part of every steam power plant. It governs the exhaust pressure of the low pressure turbines and defines the minimum cycle temperature. The heat that is extracted from the cycle steam by the condenser is tran
