A method of more accurately measuring steam turbine efficiency is disclosed in which the sealing steam in the steam turbine is re-routed so that a more accurate measure of steam turbine efficiency can be made. Some of the steam entering a turbine goes into the turbine's end pack and then ...
For instance, the Carnot efficiency of a steam turbine works at 450°C (723 K) with the water released from the condenser at 45°C (318 K) is: (6.20)ηheatengine=723−318723=0.56or56% For an HFC system operating under isothermal circumstances, the maximum efficiency is achieved ...

Improvement in isentropic total to total efficiency of a low reaction turbine stage by airfoil redesign was considered in first part of the paper. Further, modifications in the flow path of the base-line stage is considered in second part of the paper. Flow path of the baseline stage incorpora...
a蒸汽轮机是一种将水加热后形成的水蒸汽的动能转换为涡轮转动动能的机械。相较于原由詹姆斯·瓦特发明的单级往复式蒸汽机,涡轮蒸汽机大幅改善了热效率,并能提供更大的功率,至今它几乎完全取代了往复式蒸汽机。 After the steam turbine is one kind the steam energy transformation which forms the water heating ...
As deposits build up within the turbine, the normally smooth surfaces of blades become rough. The aerodynamic shape of the blade changes, therefore reducing blade efficiency!! This condition causes steam flow to be reduced and can reduce the turbine power output. Historically, the most common ...
Usage of some thermal equations of state for defining thermal and physical properties of freons is analyzed. Equation of isentropic process for the thermal Redlich–Kwong equation of state is obtained. Calculation of energy efficiency of a system with a freon-steam turbine for selected variants of...
