Calculation Submarine Hydrodynamic Coefficient by Hybrid Method

Increase in the accuracy of hydrodynamic coefficient calculation cause to increase in the prediction of vessel maneuvering ability. Different methods of determining hydrodynamic coefficients will be effective in determining the accuracy of coefficients, especially in numerical simulation. In this paper, we do planar motion mechanism (PMM) test, oblique towing test, and rotating arm test simulat...

Calculation of Steam-water Relative Permeability Using Capillary Pressure Data

Various capillary pressure approaches such as the Purcell, Burdine, Corey, and Brooks-Corey methods were used to calculate steam-water relative permeabilities using the measured data of steamwater capillary pressure in both drainage and imbibition processes. The calculated results were compared to the experimental data of steam-water relative permeability measured in Berea sandstone. The steam-...

Fault Statistics and Mode Analysis of Steam-Induced Vibration of Steam Turbine Based on FMEA Method

Steam-induced vibration is a kind of self-excited vibration which is one of the most important issues affecting the operation reliability of steam turbines. A lot of actual cases of steam-induced vibration of steam turbine were collected in this work. And steam-induced vibration fault was statistical and classified by fault reason, happened time, occurrence load and fault severity. The statisti...

Steam Turbine Configuration

Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rota...
