a fluctuation sensor that senses fluctuations in a value correlated with the gas turbine load; and a corrector that corrects the flow volume ratio found by the flow volume ratio computer with the correction value found by the correction value computer when a fluctuation in the load correlated valu...
The Mach number (M) is defined as the ratio of the fluid velocity to the speed of sound: (9.19)M=vc For most, if not all, biological applications, flow will be subsonic in which the Mach number is less than 1. In this case, a decrease in cross-sectional area causes an increase in...
In subject area: Engineering ‘Fully analytical flowrate prediction’ is the estimation of flowrate through a turbine from basic fluid and thermodynamic principles as a function of the turbine’s size, shape, and head. From: Comprehensive Renewable Energy, 2012 ...
Thermal mass flow meters excel in handling widely varying flow conditions thanks to their exceptional turndown ratio. With turndown ratios of 100:1 standard and up to 1000:1 available in some models, they can accurately measure both very low and high flow rates. This makes them ideal for appli...
In the mean value engine model proposed in1, empirical formulae, e.g., polynomial functions, are employed for the volumetric efficiency (\(\eta _{vol}\)), effective area ratio function for EGR valve (\(f_{egr}\)), turbine mechanical efficiency (\(\eta _{tm}\)), effective area rati...

turbine is also expected to affect the environment especially towards animals due to the high translational noise from the blade of wind turbine9. On another note, the energy harvesting from airflow using wind turbine has been significantly developed and its potential to generate electricity in ...
The ratio of the annually produced kilowatt-hours and of the energy theoretically producible at installed capacity during the whole year. Load rejection A sudden cessation of electrical load on the generating units, inducing the rapid closure of the turbines. Main shaft The rotating element that tr...
Most researchers kept the leakage clearance size as constant, as shown in Table 5. Additionally, some researchers defined the leakage clearance size as a function of rotational speed and pressure ratio [50,57]. Table 5. Clearance sizes used by different researchers in the scroll machine model. ...
